Yobgod Ababua has been ecstatic lately. He talked with the spouse lately. He had a wonderful drink lately. He slept in a good bedroom recently. He formed a grudge recently.

He is a citizen of The Accidental Town.

He has rough stubble and a neatly trimmed beard. His short brown hair is wild. He has pale skin.

Yobgod likes galena, billon, pipe opal, ice wolf leather, the color green, waves, gauntlets, geese for their formation flying and hyena monsters for their bloated appearance.
He absolutely detests fire snakes.

A sturdy creature fond of drink and industry.

{{human}}

The '''military''' is one of the most important aspects of a successful fortress. Even with many {{l|trap}}s, {{l|bridge|drawbridges}} and {{l|magma|other defenses}}, your military will still need to fend off {{l|goblin}} {{l|siege}}s, {{l|megabeast}}s, {{l|titan}}s, and fiendish {{l|Giant cave spider|underground}} {{l|Forgotten beast|beasties}}. Using a combination of {{l|squads|squad orders}} and {{l|scheduling}}, you can set up an elaborate offensive, defensive, or balanced military structure for your {{l|equipment|well-equipped}} {{l|soldier}}s to follow. Turning your dwarves from {{l|immigration|useless migrants}} into bloodthirsty killing machines never hurts (unless you're the enemy).

For quick reference: from the main menu the '''military''' screen is accessible through the {{k|m}} key, the '''{{l|squads}}''' screen is accessible through the {{k|s}} key, the '''points/routes/notes''' screen is accessible through the {{k|N}} key, and the '''{{l|burrows}}''' screen is accessible through the {{k|w}} key. The military screen and all its tabs are mouse-compatible, and can be navigated through mouse clicks rather than strictly keys (when in windowed mode).

=Creating a Military=

While far more confusing than before, the new military system makes up for its initial impenetrability with a huge increase in versatility. Squads can be assigned, reordered and restructured at will, dwarves can be set to equip a highly-specified uniform along with the rest of their squad or stand out and equip something unique, and you can give incredibly detailed commands and programming to your squads to follow out based on time of year, circumstance, location, and user convenience. That being said, there's a lot to be learned.

This article is about the general aspects of what comprises a military. For more detailed information including specific keypresses, see the associated article expanding on a subject.

==Squads==

''Full article: {{l|Squads}}''

'''Squads''' are the groups of soldiers that make up your military. Your military is now led by the appointed '''{{l|militia commander}}''' and has many other squads led by '''militia captains''' under him. Creating a squad in the military screen is one of the first things you should do when starting your military.
*For some reason your '''{{l|leader|expedition leader}}''' can not be appointed as a militia captain or commander. He can still be assigned to a squad as a regular soldier however. It is unknown if this is intended behavior.

==Equipping Soldiers==

''Full article: {{l|Squads#Equipping Soldiers}}''

Rather than simply pick a level of equipment and hope your dwarves pick up the right stuff, you can select what your dwarf will wear by item type or specific item, or create a new uniform template and apply it to a dwarf or entire squad all at once (much like a template). Even the material and color of your soldiers' uniform is configurable. You can create identical armored units with intimidating red cloaks or just slap something together based on need and circumstance. Even artifact weapons/armor are now selectable - luck and micro-management have been removed from the equation.

In the early stages of your fort your dwarves will equip themselves, but once enough migrants (13, making your population 20+ dwarves) have arrived your fortress will require an '''{{l|Arsenal_dwarf|Arsenal Dwarf}}''' (designated in the nobles screen) to manage your armory. The Arsenal Dwarf serves the role of quartermaster; without him your dwarves will be unable to change their equipment. Once you have a dwarf selected, make sure to give him an office - like a {{l|manager}}, an Arsenal Dwarf will need to sign off on equipment changes before they can be made.

Note that if you don't have an option for an Arsenal Dwarf, it just means your fort isn't big enough to need one yet. Dwarves will equip themselves until your fortress grows too large - just keep an eye on the nobles screen every time you get migrants, and assign an Arsenal Dwarf when you need one.

*If your Expedition Leader/Mayor is killed it can cause all unassigned nobles to vanish from the nobles screen. This could cause your arsenal dwarf position (among others) to be unavailable. A new expedition leader should eventually arrive, although this may take several years. {{version|0.31.02}}
*There have been reports of the Arsenal Dwarf not appearing despite the population criteria being fulfilled. This is likely caused by your Expedition leader/Mayor being absent.{{version|0.31.02}}

=Directing Soldiers=

Getting your military to actually ''do'' something is a lot more difficult than it once was; gone are the days of simply designating a barracks and letting your recruits have at it. It is now possible to give your squads different monthly '''schedules''', create different '''alert levels''' which will cause squads to follow out new user-programmed instructions depending on circumstance, give '''direct orders''' to '''attack''' one or more specific targets or '''move''' to a specific location, or follow '''patrol routes''' and '''stations''' with greater accuracy.

There is now a clear discrepancy between ''active'' orders and ''passive'' orders-- the latter is programming that a dwarf will follow to the letter and acts more as a defense method, and the former is used for taking the fight to the enemy. The ''squads'' menu is predominantly used for active commands, and the ''alert'' and ''scheduling'' menus are used for passive commands.

==Active Command==

''Full article: {{l|Squads#Direct_Commands|Squads#Direct Commands}}''

In the new military, soldiers operate much more like part-time militiamen than full-time warriors. When soldiers are not passively doing their civilian duties or following their schedule programming, they can be actively sent to do small tasks to aggressively defend your fortress. After these orders have been carried out or cancelled, your dwarves will happily return to their passive programming as if they were never interrupted. It is possible to select multiple squads or specific dwarves to carry out these orders.

Your forces can be commanded to carry out two types of orders: '''Move''' orders and '''Attack''' (or '''kill''') orders. Move orders are much like the 'station squad' command in previous versions; your selected dwarves will run to wherever you've sent them. Similarly, attack orders will select an enemy (by location on screen, general area on screen, or list) and send your dwarves charging off that way.

Soldiers following orders will attack any hostiles they encounter on their way to their destination as well as wild animals and whatever other creatures they might encounter, whether you like it or not. As a result it is very difficult to attack members of an enemy group with any sort of precision, and if your dwarves cannot take down their target there is no real way to get them out of combat; it's do-or-die. It is unknown whether this is a bug or a feature.

Orders can be cancelled through the squads screen, but your dwarves tend to be so enthusiastic that they'll just ignore you in their bloodlust. This is likely a bug.

==Passive Command==

''Full article: {{l|Scheduling}}''

The new '''alert level''' and '''scheduling''' system is a new feature that is both incredibly versatile... and, initially, completely impenetrable. Once you learn the system, though, you will find that you barely need to manage your military at all. Effectively, a schedule is programming for a squad to follow within an alert, broken up by month, and alerts can be quickly and easily swapped in order to apply different schedules of your choosing to different squads of your choosing. Without scheduling, alert levels would do nothing; without alert levels scheduling would be horribly inefficient; the two functions co-exist and rely on each other.

It is now possible to give your squads different monthly schedules, create different alert levels which will cause squads to follow out new user-programmed instructions depending on circumstance, give direct orders to attack one or more specific targets or move to a specific location, or follow patrol routes and stations with greater accuracy. The entire system (including alert names) is completely configurable, and in time you will find yourself using complicated scheduling to rotate squads between training and defending/patrolling specified areas over the course of a year without any user input, or to start defending the fort entrance or trader route with a few easy key presses.

Civilian alert levels are also possible - civilians can be restricted by '''{{l|burrow}}''' to where they can roam should the need to tuck them away into a panic room arise. The 'entrance dance' bug of the previous version has also been removed - if a dwarf restricted to a burrow is not there, he will do his best to make the journey.

The scheduling screen is broken up into a list of squads, months, alert types and '''order criteria'''. Each order (applied to one month; multiple orders can be stacked on one month as well) can be given criteria to define how many dwarves within a squad will follow its programming at once, allowing you to make a few dwarves out of the squad active at a time while the rest go about their business or to make the entire squad always active for a matter of the utmost importance, foregoing food, sleep, and booze. You can also choose which positions in a squad the order will prefer to utilize when forcing a squad to follow it.

Four types of orders can be given (as well as the 'inactive' command), defining different types of patrolling or stationary defending. Squads can spar and be given combat demonstrations in the '''{{l|barracks}}''', defend a '''{{l|burrow}}''', patrol a '''route''', or defend a single '''station'''. The monthly schedules can be named so as to better suit your needs, and a new (if still a bit buggy) copy/paste system has been introduced to eliminate some of the tedium in creating fancy scheduling for many months. The display can also be flipped around.

Barracks can now serve the needs of multiple specific squads at once. A barracks can be defined as a place to train, sleep, store squad equipment, store individual equipment, or any combination of the above, in any weird overlapping combination of barracks you like. Barracks are still necessary for training, but due to a bug it appears that your dwarves will only train when Inactive, despite what the Train command may have you believe. Marksdwarf training also appears to still be a bit glitchy.

When dwarves are being ordered to train, squad leaders will set up training classes for particular skills, or they will have dwarves spar. Any dwarves in the squad that don't qualify for these will default to individual training. In the current release, training classes are bugged where if a squad leader sets up a training class, he will wait forever (Or until you change his orders) for students, even if nobody shows up. Likewise, if students decide to request a class and the squad leader is doing individual training, they will wait for him to finish, even if they start starving. Thus, at the moment it's best to alternate your forced training schedules with downtime so the longest a dwarf will be stuck waiting is a game month (which isn't long enough to die), or just leave them off duty all the time and have them do individual training only, at least until this issue is fixed.

=Reported Military-Related Bugs=
{{version|0.31.02}}
* Copying and pasting an empty order onto a non-empty order causes a crash. -- '''Fixed''' {{version|0.31.03}}
* Going to the military-schedule-grid screen and selecting your inactive alert group causes a crash. -- '''Fixed''' {{version|0.31.03}}
* Accessing 'Pri/Assignments' ({{k|m}}, {{k|e}}, {{k|U}}, {{k|P}}) when no squads are formed causes a crash. -- '''Fixed''' {{version|0.31.03}}
* If one of your soldiers equips a dagger it causes an immediate crash when you select that squad in the military screen. Editing your raw files and replacing [SKILL:DAGGER] with [SKILL:SWORD] is a workaround that prevents this crash.[[http://www.bay12games.com/dwarves/mantisbt/view.php?id=378]]
* If your Expedition Leader/Mayor is killed, all unassigned noble positions vanish.
* Soldiers who have been killed are not removed from their squads. You can see how many dead soldiers you currently have by comparing the number of dwarves in your squad(s) against the number found at the top of the military screen.
* When selecting new dwarves to place in a squad the cursor always returns to the first available dwarf instead of remaining where it is.
* The list of dwarves available to join a squad includes dwarves that are already in a squad.
* Soldiers who have completed a kill task do not cancel their kill task. This may be intentional.
* There are still various problems with dwarves not equipping what they should; notably marksdwarves (who try to train not with archery practice but by sparring with crossbows as blunt weapons).
* Dwarves that are training and forced to stop (for example with deconstruction the barracks) will go into "no job" for eternal, they wont count to idle, just like "on break" ones, but will never ever lift a finger again... ever, neither for training nor civilian. they still will go for kill or move orders.

v0.31:Thief

2010-04-29T19:40:47Z

Yobgod:

{{av}}
{{human}}
In Fortress mode, a '''thief''' is a disgusting dishonorable creature that can skulk around the map unseen until detected. When a thief is detected, the game pauses with an identifying {{L|announcement}} and moves the game view to include the threat.

''(A full {{L|military}} response is both complex and slow. If you are new to version 0.31, and simply want to send your nearest dwarves after a thief, see {{L|Attack}}.)

There are two types of intelligent thieves: '''{{L|kobold}} pilferers''' and '''[[goblin]] baby-snatchers''':

:'''Kobold thieves''' can start appearing quite early (first year) and will sneak right past all of your {{L|trap}}s, only triggering them if they are injured during their escape attempt and happen to fall unconscious. They are detected when they move adjacent to a {{L|dwarf}}, guard {{L|dog}} or other tame {{L|animal}}. Armed with only a large dagger, they offer little threat to anyone - an untrained dwarf or dog should be able to take them down, but extreme bad luck is always a possibility in any {{L|combat}} situation. While they sometimes steal low value items left outside (intentionally or not), there seems to be a mechanism that makes them target other, higher value items inside instead, too. (aka completely random)

:The announcement for a kobold thief is...
::{{Gametext|Thief! Protect the hoard from skulking filth!|#f00}}
:...and the game will zoom to a section of your fortress with a small grey "'''k'''" visible - that's your intruder.

:Unlike kobolds, '''Goblin snatchers''' happily run into any kind of trap. They are detected the same way kobolds are, plus cage traps trigger the announcement. Armed with an iron dagger they should be approached with a little bit more caution, but any average soldier should take them down unharmed. When they get their hands on one of your beloved(?) children, they will stuff them in a bag they carry with them for that purpose. (Needless to say, this creates a very {{L|thought|bad thought}} in the parents of the lost child.) The child is considered part of the snatcher's inventory -- in particular, if the goblin is caught in a cage trap, the child will be caught with him. Left in this condition for too long, the child may go insane.

:The announcement for a goblin child-snatcher is...
::{{Gametext|Snatcher! Protect the children!|#f00}}
:...and the game will zoom to a section of your fortress with a small grey "'''g'''" - if you use {{k|v}} or {{k|u}}, these will be listed as "goblin ''thief''" but they're cut from the same stuff and should be terminated with equally extreme prejudice.

:If caged by a trap, the zooming may only reveal a flashing {{L|cage}}, a "'''‼'''".

Both kinds will usually come in small groups of about 1 to 4 individuals. They try to escape once detected and only fight when cornered. Their ability to sneak into your fortress is not to be underestimated; locked doors do not slow them down, although similar barriers that are linked to a lever (and are closed) will. They can lurk around the map for quite some time and wait for their opportunity, even when they are already inside your fortress. They may arrive more or less simultaneously with sieges or ambushes, distraction and general turmoil working in their favor. Guarding any entrance with {{L|restraint|guard animals}} is a safe countermeasure, though. A successful theft of item or child will be announced once the thief leaves the map.

Spotting the thief is winning the battle, but catching and killing them just feels better. A typical thief can outrun a "{{L|Attribute#Agile|very agile}}", unarmoured dwarf, but can only just keep their own against an "extremely agile" unarmoured pursuer. Sending more than one respondent to cut off any retreat may yield a more satisfying result.

Certain "playful" {{L|creatures}} will also try to steal items from your hoard, if left open to more general traffic. These include {{L|raccoon}}s, which tend to be solitary, and groups of {{L|rhesus macaque}}s and {{L|mandrill}}s (which aren't just playful, but downright dangerous). In addition, {{L|black bear|bear}}s and {{L|gnome}}s will try to steal your {{L|alcohol|booze}} if they can get at it. None of these animals has any special ability to avoid standard traps or bypass locked doors.

:''(:'''''Note:''' Wagons appear to be absent in DF 31.03. Toady has not yet signaled if this is a bug or not, but they are in the RAW files.)''{{verify}}

'''Trading''' in Dwarf Fortress first occurs in the first {{L|Calendar|autumn}} after establishing your fortress, with the arrival of the {{L|dwarf|Dwarven}} {{L|Trading#Caravans|caravan}}. Trading is a good way to acquire resources that are not available or are rare in the local area. It also allows for more freedom in selecting starting gear or purchase of additional skills for the expedition party, because items can always be obtained through trade later.

'''Trader''' is the term used at your Trade Depot to refer to your fortress {{l|Broker}} when dealing with merchants in a visiting caravan ({{key|r}} - "''Trader requested at Depot"''). As a {{L|profession}}, the term usually only applies to visiting merchants, or to a dwarf whose highest {{L|skill}} is {{L|Appraiser}}.

== Trade Depot ==
Building a '''Trade Depot''' ({{K|b}} - {{K|D}}) is a requisite for trade with caravans that arrive at your fortress. Trade depots can be created from almost any material, and construction requires the {{L|Architecture}} skill along with the appropriate craft labor ({{L|Carpentry}}, {{L|Masonry}}, or {{L|Metalsmithing}}). There must be at least 10 spaces between the Depot and the edge of the map.{{version|0.31.01}}

While it may be convenient to build a Trade Depot outside at first, it is usually a really good idea to move it inside or build walls, bridges and other fortifications around it to protect caravans and your goods from animals (guzzlers), {{L|thief|thieves}} and {{L|goblin}}s.

Once built, hit {{K|q}} to bring up the building interaction mode, and then move your cursor over the Trade Depot to gain access to the following options:

=== Move Goods to/from Depot ===
{{K|g}}: This command becomes active when a caravan arrives on your map. This screen menu is similar to the {{L|stock}}s menu ({{K|z}} - Stocks). This is where you select what items you want to trade with the caravan. If you have particular items you want to sell to the caravan, you can {{K|s}}earch for it. This is convenient if you want to export all your prepared meals or finished goods. Also shown is the culling on {{K|m}}andate option. The move to depot screen will not show things that violate an export {{L|mandate}}. By pressing {{K|m}}, it will change to Ignoring {{K|m}}andates, and you can select banned items for export. For example, if your {{L|mayor}} has a mandate banning the export of iron, this screen will hide bins that contain iron items. By changing this option, all iron items will be shown.{{Verify}}<br\> <br\>After selecting items and exiting the screen, {{L|job}}s will be queued to move the items to the depot. All dwarves, regardless of {{L|labor}} settings, can move goods to the depot. Items that have not been moved will show [PENDING], while those that have been brought to the depot and are ready for trade and will be marked as [TRADING]. <br\><br\>Items selected for trading will remain at the depot until the caravan leaves. Alternatively you can select the item again. Once no longer required at the depot, items will be available for use or hauling to stockpiles as normal. If you don't want all the items to be returned to their stockpiles, you can optionally {{K|f}}orbid them by looking at the {{L|Controls_guide#View_items_in_buildings.2C_t|i{{K|t}}ems}} in the depot.

=== No trader needed at depot or Trader requested at depot ===
{{K|r}}: This requests a dwarf to come to the depot. To conduct trades with caravans, a trader must be present at the Trade Depot. Once requested, a dwarf will make their way to the depot, and remain there until released with this setting, or the dwarf decides to drink, sleep, or eat.

=== Only broker may trade or Anyone may trade ===
{{K|b}}: This setting determines who will perform the trade. If '''Only broker may trade''' is active, then only the {{L|Broker}} {{L|noble}} will respond to the trader request. This can become a problem when the broker is sleeping or otherwise occupied, but dwarves with low {{L|Broker skills}} will receive poorer deals when trading. If anyone may trade is selected, and someone other than the broker becomes a better {{L|appraiser}} than the broker, the broker's appraisal skill is still used.

=== Trade ===
{{K|t}}: This option becomes available once the caravan and your trader are both at the depot. It begins trading.

<s>
Do not build two or more Trade Depots, as then neither will work properly.</s>{{Verify}}Assuming false. Depot accessibility screen now features information about multiple depots (all depots accessible vs depot accessible)

Everything that is on your map belongs to you, except:

* the items of non-fortress members (only if they are alive, when they are dead they belong to you if you claim the items),{{Verify}}
* the items that are in trade wagons or on merchant animals{{Verify}}
* the items that are on the trade depot (they belong to nobody until they are moved out of it)

So, merchant goods that ''were'' on the trade depot belong to you if they are not on trade wagons/merchant animals. So a {{L|Cheating|little hint}}: when the merchants have finished unloading, remove the depot!

==Trading Flowchart ==
{{:Trading/Flowchart}}
After entering the trade menu, select the items to offer from the right, and the desired items from the left. All caravans have a weight limit which cannot be exceeded, and the allowed additional weight is displayed in the lower right corner. If the acting broker has at least Novice or better {{L|Appraisal}} skill, the value of all items will be displayed. Once the proposal is ready, press {{K|t}} to make an offer, but merchants will not agree unless they make adequate profit. Be sure to use '''trade''', not '''offer''' {{K|o}}, as this will make a gift of the selected items. The amount of acceptable profit is determined by the broker's {{L|Broker skills|skills}} and the merchant's mood, described below. Merchants may attempt to propose counteroffers if they do not accept the proposal, which can then be accepted, rejected, or further amended by the broker.

<s>A good rule of thumb for inexperienced brokers is to give merchants a 50% or better profit. For example, if the desired goods are worth 500☼, make sure their profit is at least 250☼ (which would make the total worth of goods marked on your side 750☼). This should ensure that the merchants are happy with the trading and that they accept the trade immediately without making ridiculous counteroffers.</s> With more experienced brokers or pleased merchants, even marginally profitable trades can be successful, and counteroffers can be rejected safely, offering the same trade again. Note however that a low profit margin for the traders may not be desirable - it has been suggested that both export and profit numbers influence the size of next years caravan and, in the case of the dwarven caravan, immigration numbers.{{Verify}}

Goods brought from caravans do not have base quality higher than superior, but decorations on a good may be of any quality.{{Verify}}

== Trading cue colors ==

* Items in brown have been created (or modified) by your fortress. They can be traded away or offered as a gift.
* Items in white were created by another source. They can be traded, but if one of these items has been selected, the entire selection cannot be offered as a gift.
* Items in purple are under a no-export mandate and should not be traded away unless exceptional circumstances (or masochism) push you to do this.{{Verify}}
* Items in green have just been gifted to the caravan and they will not trade it back.
* Items in red have been seized from another caravan and cannot be traded as is; you will need to decorate them or turn them into other items for them to become "valid" trading items. However, usually a caravan from a different civilization will accept stolen goods without changing them first.{{Verify}}

== Merchant mood ==
If your broker has Novice or better {{L|Judge of Intent}} skill, there will be a line added below the merchant's dialogue describing the caravan's attitude. Their attitude rises with successful trades (especially if they get lots of profit) and falls when you propose deals they don't like.

* (trader) seems ecstatic with the trading
* (trader) seems very happy about the trading
* (trader) seems pleased with the trading
* (trader) seems willing to trade (Default, at least for humans)
* (trader) seems to be rapidly losing patience
* (trader) is not going to take much more of this
* (trader) is unwilling to trade

The happier you make a merchant, the less profit margin he will demand in a trade. If merchants reach the lowest level, no further trade will be possible, and they will immediately pack up and leave your depot. Since annoyed traders are more likely to reject deals, you should be generous in initial negotiations. Skilled negotiators seem less likely to offend traders with unsuccessful deals.

An easy way to capitalize on this mood system is to perform several partial trades. First trade for a few items, offering goods twice the value of the items you ask for (eg, offer 2000☼ for 1000☼ of his stuff). This will likely make the merchant ecstatic about trading with you. Exit the trade screen, unpause briefly, and then return to trading with a vengeance. With the merchant in such a good mood, he is more likely to counteroffer than reject a trade outright.

== Seizing items ==

Pressing {{K|s}} from the trade menu will seize the selected items of the merchant's. If you seize goods from a caravan, the merchant will respond "Take what you want. I can't stop you." and then leave immediately without the seized goods. Items cannot be seized from the dwarven caravan, and other races will not buy goods stolen from one of their caravans (then marked in red) unless they are tricked into asking for them via counteroffer, or the items are "laundered" by decoration or used to create other goods. Seizing goods will hurt diplomatic relations, but is not grounds for an automatic {{L|siege}}.{{Verify}}

Pressing the seize button while no goods are selected will result in the merchant interpreting your seizure as a joke. This apparently does nothing to benefit or hinder your trading.{{Verify}}

As a side note, if you deconstruct your trade depot with a caravan in it, the wagons will be killed and all the caravan's items will drop to the ground, to be readily hauled away by your Dwarves. This does not mark the items as stolen, and the caravan will leave. However, ''next'' year's caravan is partly based on the profits from the previous year - so if you are relying on that race's caravans for needed items, you're hurting yourself in the long run.{{Verify}}

Another way to steal without marking as stolen is to forbid the trade depot just before they leave, causing them to leave their goods at the depot.{{Verify}}

Note that the civilization attached to a particular caravan will keep track of the value of items the caravan was carrying when they set out to trade, and they will compare this value with the value of items they return home with. Regardless of what method you use to confiscate items from a caravan, even if you came to possess the goods through no fault of your own (an {{L|ambush}} killed the caravaners, for example) the parent civilization may decide that you stole from them and send a {{L|siege}} instead of a caravan the following year. It is prudent to take measures to protect caravans visiting your lands!{{Verify}}

==Offering items==

{{key|o}} You can also give away items, as gifts to the leaders of the {{L|civilization}} you are trading with. This presumably helps relations between yourself and the other faction. The exact effects are unknown but it is believed that offering goods increases the quantity and variety of trade goods brought by next year's caravan. Also the {{L|King}} usually requires offerings to be made before his arrival.{{Verify}}

'''''Note:''' There are currently no benefits to offering goods to your king; the game developers have stated that this is to be changed in future versions.'' ("''Req174, REASON FOR OFFERING, (Future): There's no point of offering goods to your own king right now.)"''

== Miscellaneous Trading Advice ==

* Several small trades, exiting the trade window each time, will increase the Broker's relevant skills during the early game.
* Food inside the Trade Depot can go bad. Have a food stockpile nearby so you can quickly haul goods inside.
* Thieves and thieving critters tend to follow caravans. Expect assaults and intruders.
* Be careful about asking traders to bring lots of individual lightweight items (such as meat and fish) as it can result in traders taking a very long time to unload their goods. Unless the path to your depot is extremely long, though, this is unlikely to cause significant problems.{{Verify}}

== Caravans ==
Each friendly race will send a caravan per year, linked to one season, which is autumn for dwarves, summer for humans, spring for elves. In rare cases, goblins will show up in winter.{{verify}} However, in the first year only a dwarven caravan will arrive, although it will tend to arrive later than mid-august, unlike previous versions {{verify}}. Caravans will only show up if that race considers the fortress site accessible (as denoted on the embark screen), with the exception of dwarves, who always arrive unless they are extinct.{{verify}} Caravans appear to enter the map from a random direction which does not coincide with the relative direction of the originating {{L|civilization}}, and they may appear from different directions or z-levels each year. Caravans may leave without trading if it takes too long to reach the trade depot. Caravans with wagons cannot use stairs. Caravans will embark on their journey back exactly one month after their arrival, whether they have succeeded in reaching the depot or not.{{Verify}}

Note that if traders or their animals are prevented from leaving, they will eventually go {{L|insane}}. {{Verify}}

Also worth mention is the pathing behavior of the entire caravan. If one member of the caravan reaches a block in their chosen path (ie. a raised drawbridge that was lowered when they entered the map) the entire caravan will re-path, instead of encountering the obstacle one by one.

== Liaisons ==
{{L|Liaison}}s may be sent with caravans to speak to important dwarves. They will allow you to choose the type of items that your fortress is interested in, and will focus on bringing more of that kind of item on the next caravan (however those items will also be more expensive). They will also present you with a list of the items they're willing to pay more for, which will be effective upon their next arrival.

Trade agreements can be viewed at a later time through the Civilization menu ({{k|c}}). These trade agreements are cleared when a liason of the corresponding civilization enters the screen, so they are generally not accessible after the caravan has arrived.

Note that if a liaison is prevented from leaving, they will eventually go {{L|insane}}. {{Verify}}

== Races ==
The following races send caravans.

==== {{L|Dwarves}} ====
The dwarven caravan:
* arrives in {{L|Calendar|autumn}}.
* carries metal bars, {{L|leather}}, weapons and armor, food and booze, and more. Dwarves alone may carry {{L|steel}} and steel goods.
* well guarded.
* sends a liaison who will speak with the {{L|Expedition leader}} (or {{L|Mayor}}) to negotiate prices.
* influences the number of immigrants received (if the caravan leaves intact).{{verify}}
* will not cause sieges when repeatedly destroyed or lost.
* is the only caravan to arrive during a fortress' first year.
* always arrives regardless of embark location.{{verify}}
* cannot have its goods seized from the trade menu.
* may not arrive if your civilization lacks any notable figures.

==== {{L|elf|Elves}} ====
[[Image:Evil_elves.png|thumb|400px|A typical elven caravan.]]

The elven caravan:
* arrives in {{L|Calendar|spring}}.
* carries {{L|cloth}}, {{L|rope}}s, various above ground seeds, {{L|plant}}s and their byproducts, {{L|log}}s, {{L|wood}}en goods & {{L|weapon}}s, clothing and {{L|armor}}, and may carry tame {{L|creature}}s.
* unguarded.
* does not accept some items in trade:

Elven traders do not like to be offered any tree byproducts. Forbidden items include:

* {{L|Wood}}en items, and items derived from wood (including {{L|tower-cap}} logs), such as {{L|charcoal}} and {{L|pearlash}}
* Items made from clear and crystal {{L|glass}} (because {{L|pearlash}} is used in their creation) - green glass appears to be perfectly acceptable
* Items {{L|decoration|decorated}} with any of the above materials
* {{L|Obsidian}} shortswords (since they have wooden handles)
* {{L|Soap}} (made with {{L|ash}})

Offering or trading forbidden items will cause the mood of the trader to drop rapidly, usually causing him after the first offer to refuse to trade any more that season and leave immediately. Additionally you will be called uncouth, crude, and barbaric.

However, {{L|stone}} and {{L|metal}} items, even when {{L|charcoal}} is used in production, are acceptable. Items made from {{L|silk}} are acceptable, as are all non-wooden plant-derived products such as {{L|cloth}} and {{L|thread}}. Items made of bone (totems too), horn, shell or leather are acceptable, so are meat and fish. You can also transport your goods to the {{L|trade depot}} in a wooden {{L|bin}}, as long as you do not try to sell the bin. Living animals are acceptable, as long as the {{L|cage}} or {{L|trap}} is not made of {{L|wood}}.

Be especially careful with reselling decorated items from other caravans, as non-wood/glass items may have decorations of wood or clear/crystal glass. All items that elven caravans sell are also unacceptable to sell back to elves, as the dwarves have no means of proving that they were made in an "elf kosher" way — and all dwarves know that elves have terrible memory.

==== {{L|Human}}s ====
The human caravan:
* arrives in {{L|Calendar|summer}}.
* carries metal bars, sand, {{L|leather}}, cloth, food and booze, ropes, waterskins, quivers, backpacks, bronze weapons and (wrongsized) clothing and armor, cages and a few domestic animals.
* moderately guarded.
* sends a liaison who will speak with the broker to negotiate prices if the fortress is big enough.

==== {{L|Goblin}}s{{Verify}} ====
A goblin caravan ''may'' arrive if your civilization is at peace with the goblins.

The goblin caravan:
*will arrive every season, four times per year{{verify}}
*unguarded
*brings mostly food and cloth
*does not send a liaison or a guild representative
*does not make import/export agreements

----

* All caravans (goblins too?{{verify}}) carry the more wood logs the smaller a fort's wood stockpile, independent of whether you requested them. This does not apply when the weight limit is exceded by (other) items you requested.

== Destruction ==
If caravans are destroyed (intentionally or unintentionally), the items may remain for use. Traders caught in a {{L|cave-in}} will flee as if they were attacked but will leave all the items dropped by the caravan behind. Pack animals carrying items are affected just like a normal tamed {{L|mule}} and must be killed in the cave-in for them to drop items on the ground. It is however much more likely that the pack animal(s) will only be stunned or rendered unconscious and flee shortly after recovering from the hit. Wagons will collapse if caught in a cave-in, leaving all that it was carrying on the ground as a result. Wagons can also be destroyed by {{L|ocean}} waves coming up onto the shore if you have settled in the appropriate area. The only difference between collapsing under waves or a cave-in is a higher probability of recovering items if the wagon is destroyed by a wave.{{Verify}}

While caravans can defend themselves, they don't like being ambushed. An encounter with unfriendly creatures may cause them to retreat and forget about trading with you for the season.{{verify}} Repeated caravan destruction (intentional or unintentional) will strain diplomatic relations and may result in a {{L|siege}}.{{Verify}}

== Caravan Delay ==
If a caravan has arrived at your trade depot and is unable to leave for about six months after they arrived, the merchants and animals will go insane. This can result in a bunch of merchants attacking your dwarves, or just standing around moping until they starve to death. It is not known for certain if this hurts diplomatic relations, but most likely it's the same as any case where the entire caravan fails to return home.{{Verify}}

If you have locked the caravan into your fortress to hold out against a siege, it's a good idea to station a squad of soldiers near the trade depot in case the merchants {{L|Insanity#Types|go berserk}}. You may also want to make the depot a restricted area to encourage civilians to go around it. Alternatively, you can design the trade depot using drawbridges so that it can be sealed off from the rest of the fortress during a siege.

If you want the merchants to leave safely, you can build four or more tunnels to each corner of the map, connected to your fortress only by drawbridges. As long as there is no other way to enter and exit your fortress, invaders and merchants will both go towards any tunnel that you activate. You can lock the merchants into the trade depot, and then open a tunnel entrance on one side of the map to make the invaders head towards that tunnel. When they get close to it, you can close it, and then open the entrance on the other side of the map, and let the traders out of the depot. If your fortress and depot are in the middle of the map, this will give the traders quite a head-start to get away.{{Verify}}

v0.31:Water wheel

A '''water wheel''' is a {{L|machine component}} that provides {{L|power}} via {{L|water flow}}. To build a water wheel, select {{key|b}}uild menu and choose {{key|M}}achine components. It requires 3 {{L|wood|wood}} and generates 90 net power, which can be used for operating a {{L|Screw pump|pump}} or {{L|mill}}. You can use {{L|axle|axles}} and {{L|Gear assembly|gears}} to access the power produced by a water wheel, or connect machinery like a {{L|Screw pump|pump}} or {{L|millstone|millstone}} directly.

Waterwheels do ''not'' work with waterfalls, nor in magma - it takes water that is flowing according to the DF use of the term.

''For a basic overview of how the different machine parts work and work together, see {{L|machinery}}.''

== Construction ==
The {{L|Building_designer|architecture}} and {{L|Carpenter|carpentry}} labors are needed for the construction.

A water wheel occupies 3 adjacent tiles (N-S or E-W axis, no diagonals). It is the color of the first wood selected for it, so you could build a red wheel with one piece of goblin-cap and two of fungiwood.

Although you can build a stable water wheel on solid ground, this isn't going to do you any good. For this reason, water wheels are almost exclusively built in a hanging state with gaps in the floor below. To do this the water wheel must be attached to a nearby machine component on either side of its center tile. Do not hang it from a gear assembly you wish to control with a switch, a disconnected gear assembly can't support anything and will cause the waterwheel to deconstruct.

{{L|Power}} is generated from a water wheel as long as it has {{L|water_flow|flowing}} water at a depth of 4/7 or greater under at least one of its tiles. The easiest way to achieve this is by placing the water wheel over a {{L|river|river}} or {{L|brook|brook}}. With a {{L|brook}} you must first channel through the surface since brooks have a floor of sorts over them.

You can transport the power wherever it is needed via horizontal and vertical axles and gear assemblies. It is possible to support a waterwheel by building its center next to a preexisting water wheel's center.

This is by no means the limit of water power from one location, depending on the width of your river/brook/channel you can stack many waterwheels side-by-side (really big assembles will need to be artificial as there's a limit to how wide the game created water flows get). Just remember to make sure there's a support structure in place before you place the next wheel.

== Perpetual motion ==

Due to the relatively low power draw of a {{L|screw pump}}, a ''self-powering'' assembly can be made with a water wheel that still leaves plenty of excess power for other uses. This is an {{L|exploit}} (violating basics principles of physics), and possibly a bug, but this is also Dwarf Fortress, so...

To get it working, you must start the pump manually.*

:''(* Exceptions are {{L|aquifers}}, which can sometimes have naturally occurring {{L|flow}}. This is sometimes a good thing, because then a wheel simply works by itself - or a bad thing, if, for example, you want the wheel to '''not''' provide any power while you build a pump adjacent to it. It's not clear what causes an aquifer to have flow and then keep it - it's difficult to replicate reliably, and can be lost with additional {{L|channel}}ing, so designs will have to be adapted if such are found.)''

It is good to have a ready source of water to refill the machine, as water tends to escape and evaporate, and once the water falls below a certain level, the machine stops. Below an earlier level, the power supply becomes intermittent.

===Dwarven Water Reactor===

This compact design, once started, can only be stopped (without complete de-construction of all components) by blocking the tile the pump draws water from, since the pump is directly linked to both wheels - deconstructing one wheel will cause a flood (and almost immediately cancel any job order to deconstruct the other components), and deconstructing the pump will cause both wheels to collapse (unless they are attached to {{L|machinery}} outside them, not shown). {{L|Power}} is routed up from the pump or off to the side from a wheel, where a {{L|gear assembly}} can be placed early in the power train, linked to a {{L|lever}}, to disconnect the power at that point.

The design below produces 170 surplus power (less additional power train), almost twice that of earlier designs in less than half the space. Expanded versions can produce more power, but should be planned in advance unless you're willing to tear it all down to change the configuration. A second reactor, then connected to the power train, might be better.

'''X X''' = '''Pumps from south'''

Dig the V-shaped channel and fill it with water (either from an outside source or by designating it as a {{L|pond}}). Meanwhile, construct the pump, pumping from the South. Construct the two water wheels. Start the pump manually ( {{k|q}}, {{k|Enter}} ) - if there is enough water*, the "reactor" will start immediately and the pump operator will leave. The water from the north end of the pump will spill over the top-most floor tile, filling that to 7/7 and the two tiles east and west of it to ~5/7, but will not overflow back past the water wheel to the walkway area. Note that for the upper level, no southern walls are shown as none are needed.
*''(* Estimated minimum depth to prime the reactor is 3/7 to 4/7, though this is not guaranteed.)''
* The ideal amount of water in this design is apparently 63 units of water. In other words six tiles below in the V are full up to 7/7 and three more above are also full up to 7/7 which will generate reliable flow permanently without ever losing any of that water to evaporation. An easy way to do this is to simply leave your pond fill command on after the reactor activates. They will eventually fill it up to the optimal level and stop.

''Note: If created in an aquifer, there is a chance that the channeled tiles will have a natural {{L|water flow}} - this will cause the pump to start the moment the first wheel is finished, flooding the work area for the second.''

===Mini Water Reactor===

This even more compact design is quite similar to the original Dwarven Water Reactor, but can be used in tight spots that do not need more than 80 surplus power. This plan can also be considered an extension unit to the DWR, in that it can be added to one or the other side to provide an additional 80 power to the resulting power train. Safely constructing a mini reactor to add to a previously built reactor without potential flooding and/or loss of power is possible only if you first turn off the original reactor with floor hatches. Planning ahead is a much better option, so if you're going to need more than 170 power, build a larger reactor to start with.

As stated previously, the design below produces 80 surplus power (less additional power train).

Construction of the mini reactor follows the same order as for the DWR, though the channel is slightly different and only one water wheel is needed. If this is an addition to a full size reactor or set of reactors, all channels will need to be fairly full with water to start the reactor.

v0.31:Thought

Yobgod: /* Happy Thoughts */

{{av}}

Over time dwarves will have different thoughts. In the latest version of DF, the rate at which a dwarf gains certain thoughts is controlled by personality modifiers. Thoughts have effects on the dwarf's happiness.

The change in [[DF2010:status icon|status]] that triggers bad thoughts about thirst, hunger, and fatigue can also slow the speed at which a dwarf works and moves.

To view a dwarf's thoughts, press {{key|k}}, move the cursor to the dwarf, and press {{key|enter}} twice.
Now you will see a page describing the dwarf's feelings and thoughts, physical description, and a set of phrases describing personality traits.

==Happy Thoughts==
* "Slept in a (good quality) [[DF2010:bedroom|bedroom]] recently."
* "Dined in a (good quality) [[DF2010:dining room|dining room]] lately."
* "Admired a (good quality) (object) lately."
* "Talked with a friend lately"
* "Made a friend recently."
* "Satisfied at work lately."
* "Took someone to bed recently."

==Unhappy Thoughts==
* "Has complained of (hunger|thirst) lately."
* "Has been tired lately."
* "Slept uneasily due to noise lately."
* "Slept without a proper room recently."
* "Slept in the mud recently."
* "Was caught in the rain recently."

==Negative Thought Modifiers==
* "is quick to tire"

==Positive Thought Modifiers==

v0.31:Strange mood

2010-04-11T00:13:10Z

Yobgod:

{{av}}
{{buggy|Bugs}}
Periodically, individual dwarves are struck with an idea for a [[legendary artifact]] and enter a '''strange mood'''. Dwarves which enter a strange mood will stop whatever they are doing and pursue the construction of this artifact to the exclusion of all else. They will not stop to eat, drink, sleep, or even run away from dangerous creatures. If they do not manage to begin construction of the artifact within a handful of months, they will go [[#Failure|insane]] and die soon afterward.

==Overview==

# The conditions necessary for a strange mood to occur: ''fill in here''
# The game will pause, center on a dwarf, and announce that the dwarf has entered one of five different types of strange moods. The [[#Types|types of mood]] are listed below. While in a mood, a dwarf will display a blinking exclamation point (see [[status icons]]).
# For the duration of the mood, the dwarf will claim a workshop related to the skill that the mood affects (not all skills are eligible), kick out any dwarf who was using it, and render it otherwise unusable until the mood has been resolved. If a moody dwarf does not claim a workshop, it is because the appropriate workshop does not exist. (See [[#Skills and workshops|skills and workshops]] below to determine which workshop(s) might be required.) A moody dwarf will ''not'' be available to build a needed workshop; another dwarf with the appropriate [[labor]] designation must do so for them, if one is necessary.
# After claiming a workshop, the dwarf will set about collecting the required materials for their artifact. If the dwarf remains idle inside the workshop, it's because they cannot find the right material. Reference the [[#Demands|demands]] section to determine what may be required.
# Once all materials have been gathered, the game will once again pause and center, and the moody dwarf will begin construction. Upon completion the dwarf will create a semi-random artifact related to the skill affected and gain [[legendary]] (or higher) status in that skill (unless the mood type is [[#Possessed|possessed]]). See the [[#Skills and workshops|skills and workshops]] for information on which skills can be gained, or the [[#Artifacts created|artifacts created]] section for more details on the artifacts themselves.

== Types of moods ==
For each of the following types of moods, the first message is how the mood is [[40d:Announcement|announced]]; the second message appears in the dwarf's profile when he or she is viewed with the {{K|v}} key. All moody dwarves will have "Strange Mood" listed as their active task.

=== Fey ===
* {{Gametext|<dwarf> is taken by a fey mood!|#fff}}
: ''Has the aspect of one fey!''

This is the most basic strange mood. Fey dwarves will clearly state their demands when the workshop they are in is examined.

A fey dwarf's happiness is automatically set to 'quite content'.

=== Secretive ===
* {{Gametext|<dwarf> withdraws from society...|#ccc}}
: ''Peculiarly secretive...''

Secretive moods are the same as fey moods, except a secretive dwarf will sketch pictures of their required materials instead of clearly stating their demands if they cannot find what they need. Descriptions of all these [[#Demands|secretive requirements]] can be seen only by viewing the workshop that the moody dwarf has claimed, with {{k|q}}, and then only while the dwarf is waiting inside it. More than one "picture" is likely; these will cycle through the entire list automatically if any one is not available. (Since materials are gathered ''in order'', it's quite possible that only one of a long list is needed to allow the moody dwarf to continue on their project. If the dwarf has gathered some of the materials (seen as "tasked" when looking at the workshop with {{k|t}}), then the next in the list is what they are looking for.)

A secretive dwarf's happiness is automatically set to 'quite content'.

=== Possessed ===
* {{Gametext|<dwarf> has been possessed!|#f0f}}
: ''Possessed by unknown forces!''

Possessed dwarves have cryptic material requests, and have the unfortunate distinction of not receiving any experience upon successful construction of an artifact. It is unknown if controllable circumstances lead to a possessed mood instead of one of the more desirable fey or secretive moods. Possessed dwarves will mutter the name of the artifact they are working on once they have all the materials they need.

A possession is the only mood that does ''not'' result in a jump in [[experience]].

A possessed dwarf's happiness is automatically set to 'quite content'.

=== Macabre ===
* {{Gametext|<dwarf> begins to stalk and brood...|#777}}
: ''Brooding darkly...''

Macabre moods are similar to fell moods, but the dwarf will not murder a fellow dwarf. A macabre dwarf may require bones, skulls, and chunks/remains; if you do not happen to have any, you will have to "make" some, or let the moody dwarf go insane. Like fell moods, only unhappy dwarves can enter macabre moods.

{{Spoiler}}

== Demands ==
Once a workshop is claimed, the dwarf will begin collecting materials. Each artifact will require between one and ten materials to complete. If the moody dwarf remains idle, then the necessary materials are not available. [[Forbidden]] items must be reclaimed ({{K|d}} - {{K|b}} - {{K|c}}) before they may be used, but moody dwarves will ignore settings regarding [[economic stone]]. Press {{K|q}} and highlight the workshop to receive a series of clues about what the dwarf needs. Hints that stay active for longer than 2 seconds mean that multiple pieces of that material will be required; each single demand will be displayed for 2 seconds, so if it says "gems... shining" for 6 seconds, 3 gems are demanded. Materials will always be fetched ''in order'', so if at least one item has already been retrieved (the items will show up with "TSK" ("task") next to them when the workshop is viewed with the {{K|t}} context menu), it will usually be possible to tell what item is required next.

If you want your dwarves to construct their artifacts out of valuable materials instead of whatever useless thing happens to be close at hand, you can selectively forbid types of material through the stocks screen so that only the material you want them to use is available; though this might interfere with the normal crafting operations of your fortress, the disruption is generally short-lived (as long as you remember to unforbid them again afterwards!). You can even forbid something a moody dwarf is carrying (which may be necessary sometimes, since while they are not waiting in the workshop they will not tell you what they need); the dwarf will finish hauling it to the workshop, but then immediately go searching for another. This trick can mean the difference between a bauxite statue decorated with moss agates and a native platinum statue encrusted with diamonds.

The various demands are translated here:

Fey dwarves will sometimes ask for rock bars. This is just a typographical error, and they are actually asking for metal bars.

== Artifacts created ==
The type of artifact created will depend on the dwarf's highest skill. Masons will always create some kind of stone object, usually furniture; bone Carvers, a bone or shell object; carpenters, a wood object, etc. Miners and engravers will usually turn out a stone craft or piece of furniture; metalworkers, metal crafts, weapons, or armor (depending on the type of metalworker); weavers, an article of clothing; tanners, a leather armor or object. If a dwarf has no moodable skills, they will take over a [[craftsdwarf's workshop]] and create a bone, stone or wood craft of some type. The precise type of craft created is usually somewhat random but if a dwarf has a personality preference for a particular thing, such as gauntlets or floodgates or crowns, and that thing is an available choice given the dwarf's profession, they will generally create an object of that type.

The first object grabbed by the dwarf will be the "primary" substance; all other materials will be used to decorate the artifact. If a dwarf grabs a piece of [[chalk]] and makes a statue, for instance, it will be a "chalk statue", but an artifact can potentially be composed of bone, cloth, gems, leather, metal, shell, stone, and wood all at once. In some cases, a moody dwarf will produce an item which normally cannot be made from that material, leading to such odd constructions as an [[obsidian]] [[bed]], [[ruby]] [[floodgate]], or turtle [[shell]] [[cage]].

Once created, most [[artifact]]s will be available for use just like a normal item of its type. Artifact furniture is useful for high value [[noble]] rooms. Artifact weapons in [[weapon trap]]s can also boost a room's value considerably, as in the case of artifact trap components.

== Failure ==
If you can't provide the desired workshop and all the required component materials within a couple of months, the dwarf will go {{L|insanity|insane}}, which cancels the mood and the artifact. As if that's not bad enough, any dwarf who goes insane will soon die, one way or another.

A dwarf who is '''stark raving mad''' or '''melancholy''' is harmless to others (until they die and start a {{L|tantrum}} spiral), but a '''berserk''' dwarf will attack other dwarfs and possibly pull levers at random. You may want to station a squad nearby or assign a few war dogs to the dwarf on the chance that they will lash out. If you build your workshops inside enclosed rooms with doors you can also lock the moody dwarf in the room until he or she starves. In extreme cases, building a wall around an open workshop is the best precaution.

==Bugs==
{{version|31.02}}
* Shells are no longer produced from eating turtles or lobsters. These must now be prepared at a fishery in order to produce shells.
* Dwarves may request "rock bars" -- This is satisfied by metal bars.
* There are various other bugs related to moody dwarves not being able to find the appropriate materials. Check the bug tracker: [http://bay12games.com/dwarves/mantisbt/view_all_bug_page.php].
