A syndrome is a disease or effect that a poor, hapless creature might get through encountering certain creatures, extracts, or vindictive modders. They generally cause unpleasant and frequently fatal symptoms over a short to long period of time, but some will clear up over time or with the assistance of a doctor. A Hospital is required to diagnose and potentially treat the syndrome.

An example of a syndrome in effect. This hippo did not ultimately survive the encounter despite one bite being the only injury sustained.

1. For small creatures such as humans and dwarves, paralysis tends to result in suffocation.

2. Necrosis of the brain will eventually result in death once the brain rots away completely.

3. Evil rain typically only causes minor symptoms such as blisters, bruising, coughing blood, dizziness, fever, nausea, oozing, and pain.

4. Evil clouds either cause major symptoms (as with beast/titan/demon sicknesses) or permanently transform creatures into zombie-like forms.

5. Titans, forgotten beasts, and demons have a chance to have a randomized syndrome. These range from pointless (mild blisters from inhaling boiling blood) to instantly deadly (Severe necrosis from a contact poison attached to a breath weapon/creature made of blood.

The anatomy of a syndrome

Mechanically, syndromes are bundles of tokens attached to a material - they're confined to creature materials in vanilla DF, but it's a simple matter to add them to inorganic materials. When the material is injected, touched, inhaled, or ingested (depending on the syndrome), the creature suffers the predations of a nasty disease or poison. Here's an example syndrome, taken from the Giant Cave Spider raws.

If you are having troubles getting the syndromes to work (ie, in combat reports, getting "supersnake n/a splatters~etc"), then simply throw the venom template into the actual creature's raw, which is what the LOCAL_CREATURE_MAT actually calls on; the venom being in the same file.

   [USE_MATERIAL_TEMPLATE:POISON:CREATURE_EXTRACT_TEMPLATE]
       [STATE_NAME:ALL_SOLID:frozen giant cave spider venom]
       [STATE_ADJ:ALL_SOLID:frozen giant cave spider venom]
       [STATE_NAME:LIQUID:giant cave spider venom]
       [STATE_ADJ:LIQUID:giant cave spider venom]
       [STATE_NAME:GAS:boiling giant cave spider venom]
       [STATE_ADJ:GAS:boiling giant cave spider venom]
       [PREFIX:NONE]
       [ENTERS_BLOOD]
       [SYNDROME]
           [SYN_NAME:giant cave spider bite]
           [SYN_AFFECTED_CLASS:GENERAL_POISON]
           [SYN_IMMUNE_CREATURE:SPIDER_CAVE:ALL]
           [SYN_INJECTED]
           [CE_PARALYSIS:SEV:100:PROB:100:RESISTABLE:SIZE_DILUTES:START:5:PEAK:10:END:20]

The first line, USE_MATERIAL_TEMPLATE, is creating a new material, called POISON, using the CREATURE_EXTRACT_TEMPLATE as the basis. After this, the STATE_NAME and STATE_ADJ tokens are used to define the names and adjectives assigned to different states of the material - GAS, LIQUID and ALL_SOLID, in this case, though ALL is also a valid token. At this stage, you can use any material tags like MAT_FIXED_TEMP or similar to set further material properties, though this usually isn't necessary.

 ENTERS_BLOOD

This tag determines whether a poison enters the blood or not. If it is not included, the poison will splatter (if liquid) or flow (if gas) over the affected body part instead when injected. If you're using a contact poison, leave this out. Necessary for injected poisons.

 SYNDROME

This tag ends the material details and begins the definition of the actual syndrome.

 SYN_NAME

This one is self-explanatory - the name of the syndrome as it will appear in-game.

 SYN_AFFECTED_CLASS

This token defines what CREATURE_CLASS will be affected by the syndrome. Most creatures are classed under GENERAL_POISON. Multiple tokens can be used in a single syndrome.

 SYN_IMMUNE_CLASS

As above, but makes class immune.

 SYN_IMMUNE_CREATURE

This token defines which creatures CANNOT be affected by the syndrome - useful for addressing specific instances within a population, such as a specific caste or an individual creature that falls under GENERAL_POISON. Syntax is [SYN_IMMUNE_CREATURE:creature:caste]. ALL can be used for the caste.

 SYN_AFFECTED_CREATURE

As above, but makes creature or caste susceptible.

 SYN_CLASS

This tag sets a class for the syndrome that can be used in interactions.

 SYN_INJECTED, SYN_CONTACT, SYN_INHALED, SYN_INGESTED

This token determines the method of infection - injected syndromes must be injected via a creature attack, while contact syndromes result from any contamination of a creature by material splatter (such as blood), inhaled syndromes must be inhaled in gaseous form (such as from boiling or a creature breath attack), and ingestion syndromes must be eaten or drunk. Any combination of these tags can be used. A fun variation on the usual creature injection routine is to create a material with a SYN_CONTACT syndrome and have a creature use it for blood - this tends to end poorly for any predator that chooses to attack them.

 [SPECIALATTACK_INJECT_EXTRACT:LOCAL_CREATURE_MAT:VENOM:LIQUID:100:100]

This is one method for getting a poison into a creature. If [ENTERS_BLOOD] is applied, it will be injected into the bloodstream. Otherwise, it will just splatter over the area. Put this on a creature attack. Substance type (gas, liquid, solid) does not appear to have an effect. The numbers on the end are minimum and maximum.

CE_X, or creature effect tokens, are the real meat and bones of your syndrome. They're detailed below.

Creature effect tokens

Each and every syndrome has a number of creature effect tokens, represented by CE_X - these lovely little beauties determine exactly how the poor creature suffering from the syndrome is affected. An example CE token is as follows:

 [CE_NECROSIS:SEV:100:PROB:100:LOCALIZED:VASCULAR_ONLY:RESISTABLE:START:50:PEAK:1000:END:2000]

In this example, we have an effect that will always cause severe necrosis in whichever bodypart it touches, so long as that bodypart is vascular and that the creature is not able to resist it in some manner. The effect begins shortly after the syndrome is contracted, peaks 1000 time units afterwards, and finally ceases another 1000 time units later.

As a general rule of thumb, so long as CE_X starts the string and START/PEAK/END end it, the order of the intervening tokens isn't important.

• CE_X

The effect type. This can be a number of different tokens, as detailed in the table below this list.

• SEV:X

The severity of the effect. Higher values appear to be worse, with SEV:1000 CE_NECROSIS causing a part to near-instantly become rotten.

• PROB:X

The probability of the effect actually manifesting in the victim, as a percentage. 100 means always, 1 means a 1 in 100 chance.

• LOCALIZED (Overwrites BP tokens)

This tag causes an effect to ignore all BP tokens and then forces the game to attempt to apply the effect to the limb that came into contact with the contagion - i.e. the part that was bitten by the creature injecting the syndrome material, or the one that was splattered by a contact contagion. If an effect can not be applied to the contacted limb (such as IMPAIR_FUNCTION on a non-organ) then this token makes the syndrome have no effect. This token also makes inhaled syndromes have no effect.

• BP:BODY_PART:TISSUE (Overwritten by LOCALIZED)

Specifies which body parts and tissues are to be affected by the syndrome. BODY_PART can be BY_CATEGORY:x to target body parts with a matching [CATEGORY:x] body token (or ALL to affect everything), BY_TYPE:x to target body parts having a particular type (UPPERBODY, LOWERBODY, HEAD, GRASP, or STANCE), or BY_TOKEN:x to target individual body parts by their ID (as specified in the [BP] token). For example, if you wanted to target the lungs of a creature, you would use BP:BY_CATEGORY:LUNG:ALL. The syndrome would act on all bodyparts within the creature with the CATEGORY tag LUNG and affect all tissue layers. For another example, say you wanted to cause the skin to rot off a creature - you could use BP:BY_CATEGORY:ALL:SKIN, targeting the SKIN tissue on all bodyparts. Multiple targets can be given in one syndrome by placing the BP tokens end to end. This is one of the most powerful and useful aspects of the syndrome system, as it allows you to selectively target bodyparts relevant to the contagion, like lungs for coal dust inhalation, or the eyes for exposure to an acid gas. Not everything takes a target!

• VASCULAR_ONLY (Optional)

This syndrome only affects tissue layers with the VASCULAR token.

• MUSCULAR_ONLY (Optional)

This syndrome only affects tissue layers with the MUSCULAR token. Are you seeing a trend here?

• SIZE_DILUTES (Optional)

This token presumably causes the effects of the syndrome to scale with the size of the creature compared to the size of the dose of contagion they received, but has yet to be extensively tested.

• SIZE_DELAYS (Optional)

As above, this token has yet to be tested but presumably delays the onset of a syndrome according to the size of the victim.

The details of this table are still being thrashed out by modders, so if you have anything to add, please don't hesitate to hit the edit button!

Non-targeted syndromes will ignore any BP tokens and LOCALIZED tokens.

Token	Accepts Target	Description
CE_BLEEDING	Yes	Causes the targeted bodypart to start bleeding, with heavy enough bleeding resulting in the death of the sufferer. Some conditions seem to cause bleeding to be fatal no matter how weak.
CE_BLISTERS	Yes	Covers the targeted bodypart with blisters.
CE_BRUISING	Yes	Causes the targeted bodypart to undergo bruising.
CE_IMPAIR_FUNCTION	Yes	An organ afflicted with this CE is rendered inoperable - for example, if both lungs are impaired the creature can't breathe and will suffocate. This token only affects organs, not limbs.
CE_NECROSIS	Yes	Causes the targeted bodypart to rot, with associated tissue damage and miasma. Badly necrotic limbs will require amputation and heavy rot will eventually result in bleeding. Necrosis has some strange behavior involving bleeding to death that isn't fully understood; a 100% necrotic creature can survive fine with no non-yellow bodyparts but will die of bleeding as soon as they end a round of combat, even if they never take a hit. Because of this, fairly useless unless targeting the lungs or eyes.
CE_NUMBNESS	Yes	Causes numbness in the affected body part, blocking pain. Extreme numbness may lead to sensory nerve damage.
CE_OOZING	Yes	Causes pus to ooze from the afflicted bodypart.
CE_PAIN	Yes	Afflicts the targeted bodypart with intense pain.
CE_PARALYSIS	Yes	Causes paralysis in the affected body part. Targeted causes sluggishness and significantly reduces speed. Untargeted paralysis is 'complete paralysis' and will cause suffocation in smaller creatures.
CE_SWELLING	Yes	Causes the targeted bodypart to swell up. Extreme swelling may lead to necrosis.
CE_COUGH_BLOOD	No	This effect results in the sufferer periodically coughing blood, which stains the tile they're on and requires cleanup. It doesn't appear to be lethal, but may cause minor bleeding damage.
CE_DIZZINESS	No	Inflicts the Dizziness condition, occasional fainting and a general slowdown in movement and work speed.
CE_DROWSINESS	No	Causes the Drowsiness condition.
CE_FEVER	No	Causes the Fever condition.
CE_NAUSEA	No	Causes the Nausea condition, and heavy vomiting. Can eventually lead to dehydration and death.
CE_UNCONSCIOUSNESS	No	Renders unconscious.
CE_VOMIT_BLOOD	No	This effect results in the sufferer periodically vomiting blood, which stains the tile they're on and requires cleanup. It doesn't appear to be lethal, but may cause minor bleeding damage.

Special Effects

Several special syndrome effects take different arguments than the above. These are used for generated interactions in unmodded games, but may be used as well for any substance or custom interaction.

Token	Arguments	Description
CE_ADD_TAG	tags	Adds a tag to the affected creature. Many arguments can be used sequentially within one syndrome token. See the Interaction token IT_REQUIRES for valid tags.
CE_REMOVE_TAG	tags	Removes a tag from a creature. Supported arguments are the same as CE_ADD_TAG.
CE_DISPLAY_TILE	TILE:tile number:colour	The creature displays the specified tile and colour instead of its normal one.
CE_DISPLAY_NAME	NAME:singular:plural:adjective	Attaches a specified name to the creature's normal name.
CE_FLASH_TILE	TILE:tile number:colour:FREQUENCY:?:?	The creature flashes between its normal tile and the one specified here.
CE_PHYS_ATT_CHANGE	Attribute:percentage:fixed boost(?)	Alters the physical attributes of a creature.
CE_MENT_ATT_CHANGE	Attribute:percentage:fixed boost(?)	Alters the mental attributes of a creature.
CE_BODY_APPEARANCE_MODIFIER
CE_BP_APPEARANCE_MODIFIER	body part:APPEARANCE_MODIFIER:attribute:number]	Alters the characteristics (height, width etc.) of a body part.
CE_MATERIAL_FORCE_MULTIPLIER	MAT_MULT:material:A:B[Verify]	Makes creature affected by materials more or less by a factor of A/B. If A is 3 and B is 2, the creature will be 1.5x weaker to the defined material (can be NONE:NONE for all); if 2:3, the creature will be 1.5 times stronger.
CE_BODY_MAT_INTERACTION		Causes one of the creature's materials to trigger an interaction, generally when ingested. Several additional tokens may be specified after this: CE:INTERACTION:interaction_id CE:SYNDROME_TAG:syndrome_trigger_type (SYN_INGESTED, SYN_INJECTED, etc.)
CE_SPEED_CHANGE	speed modifier:number	Changes the speed of a creature. Speed modifier contains one or both: SPEED_PERC:percentage (this modifies a creature's in-game speed, so higher numbers are faster) SPEED_ADD:number (this modifies a creature's [SPEED:XX] token, so higher numbers are slower. Negative numbers are accepted though will only reduce a creature's speed to zero) The minimum and maximum speeds able to be created by CE_SPEED_CHANGE are 99 and 10,000 respectively.
CE_CAN_DO_INTERACTION		Makes the creature able to perform an interaction. See Interaction token. To specify the interaction, use the argument: CDI:INTERACTION:interaction name
CE_BODY_TRANSFORMATION	PROB:percentage:START:time:END:time	Transforms into another creature. PROB and END arguments optional. The target creature is specified with: CE:CREATURE:creature name:caste name Note that any wounds the creature has suffered will instantly heal upon transforming, both into and out of the target form. Undead limbs of a creature with this token will grow into a full instance of that creature.
CE_SKILL_ROLL_ADJUST	PERC:percentage:PERC_ON:percentage:	Alters the skill level of a creature. The argument PERC specifies a percentage of the creature's current skill, and PERC_ON the probability of the effect being applied.

All creature effect tokens take START, END and PROB numbers, and can be followed by [CE:PERIODIC] and/or [CE:COUNTER_TRIGGER] to restrict when they actually take effect.

• PERIODIC:period_type:min_value:max_value
• COUNTER_TRIGGER:counter_name:min_value:max_value:REQUIRED

Currently, the only valid period type is MOON_PHASE. Valid counter values are below:

Counter	Description
ALCOHOLIC	How long it's been (in time units) since the creature last had a drink of alcohol. Only present on creatures who need alcohol to get through the working day. 100800 (3 months) = and is starting to work slowly due to its scarcity 201600 (6 months) = and really wants a drink 302400 (9 months) = and has gone without a drink for far, far too long 403200 (1 year) = and can't even remember the last time he/she had some
MOUNTAIN	How much the creature minds being outdoors. 0 = likes working outdoors and grumbles only mildly at inclement weather. 1 = does not mind being outdoors, at least for a time. 2 = (no message)
TIME_SINCE_BREAK	How long it's been (in time units) since the creature last went on break. Creatures generally go at least a year (100800 time units) between breaks unless the economy is active (which never happens).
COMBATHARDNESS	How much the creature has witnessed death and suffered tragedy. Higher values are known to decrease the severity of certain unhappy thoughts. 0-32 = (no message) 33-66 = is getting used to tragedy 67-99 = is a hardened individual 100 = doesn't really care about anything anymore
ON_BREAK	How long (in time units) the creature has been on break. Once it reaches 15000 (about 12.5 days), the creature should get back to work.
CAVE_ADAPT	How cave-adapted the creature is. Increases by 1 for every time unit spent underground, to a maximum of 800000. 403200 (1 year) = going outside causes irritation 604800 (1.5 years) = going outside causes nausea
PARTIED_OUT	How long it's been since the creature has been attending a party (or how long before it gets bored and goes back to work).[Verify]
MILK_COUNTER	How long it's been since the creature has been milked (or how long before it can be milked again).[Verify]
EGG_SPENT	How long it's been since the creature laid eggs (or how long before it can do so again).[Verify]
GROUNDED_ANIMAL_ANGER	How angry (and likely to attack) an animal is from being over-crowded.
TIME_SINCE_SUCKED_BLOOD	How long it's been (in time units) since the creature last sucked somebody's blood.
DRINKING_BLOOD	How long the creature has been drinking somebody's blood (or how much longer before it's done).[Verify]

Inorganic syndromes and you!

It's perfectly possible - and quite simple - to add a nasty syndrome to a type of rock or metal - you simply add the syndrome tokens to the material definition in the same manner that you would add them to a creature material definition. The only catch is that since your hapless dwarves will only normally encounter the material in metal, gem or boulder form, a bit of creativity must be used to actually get them inside your citizens - that is, you need to make them 'explosively boil' as soon as they're mined or produced. This has the sad side effect of destroying the actual item - sorry, no highly radioactive uranium this release.

The easiest way to accomplish this is to assign the material a low boiling point, usually just under room temperature, and make sure its temperature is fixed to a point above it.

 [MAT_FIXED_TEMP:9001]
 [BOILING_POINT:9000]

Now, as soon as this substance hits the open air - by being mined, smelted or reaction-produced at a custom workshop - it will EXPLOSIVELY BOIL, flooding a small area with delicious syndrome-rich gas. Creatures who inhale the gas will be immediately hit with the syndrome you thoughtfully attached to the material definition earlier!

There are a number of other tokens you can use to control the colour and naming conventions of your syndrome material, referred to as MATERIAL tokens.

Breath attacks

Breath attacks are controlled by the MATERIAL_EMISSION interaction, like so:

 [CAN_DO_INTERACTION:MATERIAL_EMISSION]
 		[CDI:ADV_NAME:Breath custom material]
 		[CDI:USAGE_HINT:ATTACK]
 		[CDI:BP_REQUIRED:BY_CATEGORY:MOUTH]
 		[CDI:MATERIAL:LOCAL_CREATURE_MAT:CUSTOMMATERIAL:TRAILING_VAPOR_FLOW]
 		[CDI:TARGET:C:LINE_OF_SIGHT]
 		[CDI:TARGET_RANGE:C:15]
 		[CDI:MAX_TARGET_NUMBER:C:1]
 		[CDI:WAIT_PERIOD:50]

The most important part is this line:

 [CDI:MATERIAL:LOCAL_CREATURE_MAT:CUSTOMMATERIAL:TRAILING_VAPOR_FLOW]

The CDI refers to CAN_DO_INTERACTION; the MATERIAL states that this line shows what the material is. LOCAL_CREATURE_MAT:CUSTOMMATERIAL is your material, and TRAILING_VAPOR_FLOW refers to the breath attack type. Other types are seen below. Also important is this line:

 [CDI:TARGET:C:LINE_OF_SIGHT]

LINE_OF_SIGHT refers to where the target C may be; others include SELF_ALLOWED (presumably like LINE_OF_SIGHT, but with the creature allowed to target itself), SELF_ONLY (preferable for undirected attacks and TOUCHABLE (for up-close attacks, as trailing flows tend to be).

Breath Attack Types

Token	Description
TRAILING_DUST_FLOW	Lets out a cloud of solid dust. Appears to use cave-in dust physics, causing this to fling around anything it comes in contact with, making it capable of smashing creatures into the ground and flinging them over walls. Creature will attack as normal.
TRAILING_VAPOR_FLOW	Similar to the trailing gas, but easier to breathe in, and condensed, so it will collect on creatures. Creature will attack as normal.
TRAILING_GAS_FLOW	Shoots a trail of gas substance at the creature. Fairly easy to dodge. Creature will attack as normal.
SOLID_GLOB	Shoots a solid glob of spinning substance at the creature, leaving symbols similar to broken arrows. Essentially a projectile weapon. Some creatures with this breath attack will not move, preferring instead to stay and shoot globs at you, even when you are literally right next to them.
LIQUID_GLOB	Shoots a solid glob of spinning substance at the creature. Essentially the same as SOLID_GLOB. May do less damage.
SPATTER_POWDER
SPATTER_LIQUID
UNDIRECTED_GAS	Creature occasionally releases a cloud of substance. Similar to TRAILING_GAS_FLOW, but undirected, thus affecting a larger area but losing the distance. Creature will attack as normal.
UNDIRECTED_VAPOR	Creature occasionally releases a cloud of substance. Similar to TRAILING_VAPOR_FLOW, but undirected, thus affecting a larger area but losing the distance. Creature will attack as normal.
UNDIRECTED_DUST	Creature occasionally releases a large cloud of substance, which will spread and dissipate. Similar to TRAILING_DUST_FLOW, but undirected, thus affecting a larger area but losing the distance - range is roughly the same as that of a cave-in. Creature will attack as normal. DO NOT USE THIS TAG UNLESS YOU WANT TO KILL THE CREATURE AND EVERYTHING NEAR IT AND SEND PEOPLE FLYING. You know you want to.
WEB_SPRAY	Emits a burst of webs that entangle target creatures.
DRAGONFIRE	Emits a wide cone of fire that burns target creatures. For this you want FLOW instead of a material.
FIREJET	Emits a narrow cone of fire that burns target creatures. For this you want FLOW instead of a material.
FIREBALL	Emits a fireball that burns the target creature. For this you want FLOW instead of a material.
WEATHER_CREEPING_GAS	Creates a slowly expanding cloud of gas, similar to miasma.
WEATHER_CREEPING_VAPOR	Creates a slowly expanding cloud of vapor.
WEATHER_CREEPING_DUST	Creates a slowly expanding cloud of dust.
WEATHER_FALLING_MATERIAL	Causes it to start raining a particular material.

Keep in mind that you can use multiple breath attacks, which appears to make the creature choose between them at random. Creatures cannot use the WEATHER effects, these being reserved for regional interactions.
