A [[drawbridge]], when rapidly triggered on and off, can be used to obliterate some creatures or items beneath it.  The drawbridge will be destroyed if it is used to crush a creature of too large a size.

Changing your [[bookkeeper]]'s settings to maximum accuracy causes him to work furiously in his office, training quickly up to [[legendary]]. Even if this is a bug it is not really an exploit, since a) you actually want highest precision anyway b) he attains highest precision rather fast (depending, for example, on how many stones you have mined) and thus one can not train an unlimited number of, if even several, dwarves that way.

There are a variety of ways to steal cargo from [[merchant]]s without seizing it; all amount to naked theft. Tearing down the [[trade depot]] while the merchants are there is the easiest way.  

Also, marking items for [[dump]]ing, using view creature mode ({{key|v}}), the stocks menu ({{key|z}}), items in room mode ({{key|t}}), or mass dump mode ({{key|d}})-({{key|b}})-({{key|d}}) then marking the entire depot, lets you relieve merchants of their goods. Just reclaim the items from your garbage dump [[zone]] later. You can even take clothing and equipment off merchant and guards this way.

By designating a garbage pit [[zone]] instead of a [[stockpile]], you may store an infinite number of objects in a single tile by dumping them, then reclaiming them when you want to use them.

A similar effect may be achieved by building a wall two tiles in front of a catapult and digging a channel between the wall and catapult. By firing the catapult at the wall, the stone falls into the trench. The stone will pile up in the channel, putting it out of sight and out of mind. Not only does this train [[siege operator]]s, but it clears the stone that your legendary [[miner]]s leave.

Laying a field of [[trap]]s with a sufficient depth can protect your fortress from all invaders (except the ones that are trap immune) with no need to maintain a [[military]].  Traps are somehow intelligent enough to distinguish between [[pet]]s and allies while being dangerous to enemies and wild animals.

There's a convoluted way to dig down through [[semi-molten rock]] and evade the head-on encounter with [[hidden fun stuff]]. {{Verify}}

Wall off all the passageways into your lowest level at the outermost square of the map - except one, which leads to a little vestibule surrounded by fortifications.  Wave hello to the various ungainly "[[forgotten beast]]s" which accumulate inside.

== Perpetual motion water-wheel ==

Due to the relatively low power draw of a {{L|screw pump}}, a ''self-powering'' assembly can be made with a {{L|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...

 

 

:''(* Exceptions are {{L|aquifer}}s, 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.

  '''Key:'''

 

 

 

 

 

 

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.

 

 

The reactor can be safely halted either by blocking the tile the pump draws water from or "overloading" the reactor (since drawing more power than the reactor supplies will stop the pump that keeps the cycle going until the load is reduced and the pump is manually restarted by dorf-power),  More drastically, the reactor will obviously be halted by deconstructing the pump.  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}} can routed up from the pump or off to the side from a wheel; the bottom of the pump is difficult to access without danger of water escaping.  Routing power from a wheel is typically safe in practice, but it's not impossible for a small amount of water to escape the reactor if it is temporarily overfilled.  Power can also be routed out of the reactor via a gear or horizontal axle ''over'' the tile the pump draws water from with neither interference in the pump's operation, danger of flooding, nor increased difficulty in designating and using pond zones to initialize the reactor.  In either case, it's typically wise to place a {{L|gear assembly}} linked to a {{L|lever}} early in the power train in order to allow disconnecting the power at that point, as opposed to needing to halt the entire reactor to stop the power supply.

 

Expanded versions can produce more power, and can be added later with minimal advance planning; such extensibility is easily attainable by placing disengageable gears on either side of the two water wheels, then attaching minireactors at your leisure, or halting the original reactor by other means. Alternatively, it may be easier to simply produce a second reactor, then connect to the power train at another location.

 

 

 

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.

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.

A complex but extremely modular version of the reactor, capable of easily adding more wheels by expanding the design slightly. It is also capable of moving across any number of Z-levels, and can act as a {{L|Screw_pump#Pump_stack|pump stack}} if needed.
