==Blunt==
If a strike from an attack dealing blunt damage is sufficient to destroy the struck [[body parts|body part]], damage can propagate to the parent part of the destroyed part, if and only if that parent part is considered an outside part. How the damage is divided between the two attacks is currently unclear. This allows blunt damage to deal significant damage to important body parts even if they were not the part directly targeted.

Additionally, if a blunt attack hits the parentless body part of a target, e.g. the torso on [[human]]s and most other pawns, there is a small chance to [[#Stun|Stun]] the target. This chance depends on the percentage of the body part's maximum HP that the attack inflicted as damage. It is determined by the following curve. I.e. if a single strike does 90% of the maximum, not remaining, HP of the torso to the torso of a pawn, it has a 15% chance to be stunned.

Alternatively, if a blunt attack hits a body part of a target that a is source of consciousness, e.g. the brain on [[human]]s and most other pawns, there is a larger chance to [[#Stun|Stun]] the target. This chance depends on the percentage of the body part's maximum HP that the attack inflicted as damage. It is determined by the following curve. I.e. if a single strike does 50% of the maximum, not remaining, HP of the brain to the brain of a pawn, it has a 100% chance to be stunned.

In both cases the stun duration appears to be 0.66s

If neither the parentless body part nor a consciousness source are hit, no stun occurs.

Eyes specifically have a 0% hit chance factor against blunt damage, meaning they will never be hit by a blunt attack.

|}

==Bomb==
Bomb damage is done by a variety of explosive weapons and is additionally effective against buildings. The default damage is 50, with 0.1 AP multiplier, and a default stopping power of 0.5. It does 4x Damage to Plants and to impassable buildings such as Nutrient Paste Dispensers and 2x to passable buildings such as armchairs. Additionally, [[Wall]]s specifically have an additional 2x multiplier, stacking with the previous 4x, for a total of 8x damage.

==Burn==
Identical to [[#Flame|Flame]] except that it cannot ignite targets.

==Demolish==
Demolish damage is done by [[breach axe]]s and is additionally effective against buildings. It does 10x Damage to buildings, but it otherwise identical to Blunt damage.

==EMP==
{{Image wanted|reason=Stun mote and electrical sparking effect}}
EMP damage is a fairly unique form of damage that does no direct harm to living pawns, but temporarily stuns mechanical pawns and some objects.

The weapons that deal EMP damage include:
* [[EMP grenades]]
* [[EMP launcher]]
* [[EMP shell]]
* [[IED EMP trap]]
* [[Zeushammer]] {{RoyaltyIcon}} 
* [[Persona zeushammer]] {{RoyaltyIcon}}
Additionally, when destroyed the [[Condition causer#Defoliator|Defoliator]] condition causer will release a EMP blast with a 9 tile radius.

When inflicted, EMP damage will stun [[mechanoid]]s and [[turrets]], including [[mortar]]s and both human and mechanoid turrets. Stun duration is directly proportional to the EMP damage inflicted on the target at a ratio of {{ticks|30}} of stun per damage. Most sources do 50 EMP Damage. Zeushammers do 9 EMP damage, and EMP launchers have a base damage of 50 but varying by [[quality]].

After being stunned, mechanoids become 'Adapted' and gain immunity against further stuns for {{ticks|2200}}. Immunity is applied on stun, and will not be extended by stunning an adapted or already stunned mechanoid. This time begins ticking down when the stun is applied, and thus the post-stun Adapted duration is {{ticks|{{#expr: 2200-(30*50)}}}} for most sources. Turrets do not become adapted.

EMP damage instantly breaks [[shield belt]]s, which will then recharge using their regular mechanics just as if the shield was depleted by regular damage.

Against [[low-shield pack]]s, EMP projectiles either hitting the shield itself or EMP damage done to the burnout low-shield object will disable the shield for 9 seconds, during which time the burnout timer will still count down. Note that an EMP's area of effect overlapping with the projected shield will not disable it - a projectile must hit the shield or the EMP damage must be dealt to the structure itself.

Additionally [[mech low-shield]]s and [[mech high-shield]]s in [[Mechanoid cluster]] {{RoyaltyIcon}} will be disabled for {{ticks|1080}} when hit with an EMP, including when intercepting an EMP mortar shell. 

EMP damage inflicts [[brain shock]] on pawns with the following implants, knocking them unconscious:
* [[Learning assistant]] {{RoyaltyIcon}}
* [[Neurocalculator]] {{RoyaltyIcon}}
* [[Circadian assistant]] {{RoyaltyIcon}}
* [[Circadian half-cycler]] {{RoyaltyIcon}}

EMP damage inflicts vomiting on pawns with the following implants:
* [[Detoxifier stomach]] {{RoyaltyIcon}}
* [[Nuclear stomach]] {{RoyaltyIcon}}
* [[Reprocessor stomach]] {{RoyaltyIcon}}

Using EMP attacks against friendlies counts as an attack, even if they aren't hurt. 

If an EMP attack does more EMP damage to a mortar than the it has remaining HP, the mortar will explode.

== Flame ==
Flame damage has a default damage of 10 and typically has no armor penetration at all. If any damage is dealt by flame damage at all, i.e. it is not fully negated by [[Apparel#Protection|protective apparel]], there is a chance to [[Fire|ignite]] the pawn. 

This chance does not scale with the damage done i.e. a partial mitigation does not reduce the chance. However, it does scale with the [[Flammability]] of the target, and is defined by the following graph:
{| class="wikitable"
|-
! Ignition Chance per Target Flammability
|-
| {{GraphChart|width=200|height=200|xAxisTitle=Target Flammability (%)|yAxisTitle=Ignition Chance (%)|type=line|x=0, 10, 30, 100 |y1=0, 7, 100, 100}}
|}

For example, a normal human with a flammability of 70% and so has a 100% chance to ignite if any flame damage is taken, while a human wearing [[phoenix armor]] has a flammability of 2% and so has a 1.4% to ignite if any flame damage is taken. 

If the pawn is ignited the size of the [[fire]] is randomly selected between 15% and 25%, which affects the diffculty of putting it out and the chance to spread.

== Scratch ==
Scratch damage does damage differently depending on what part is initially targeted.

If the part targeted is internal, then a count is made of all parts from the targeted part, and that part's parent, and that part's parent, etc. until a part that is external is found. The damage dealt is then evenly divided among these parts, including the targeted part and the final outside part. Note that in testing, no scratch attack was seen initially targeting an internal part. It is unclear if this is even possible to occur in game.

If the part targeted is external, then a list is created including: the originally targeted part, the children parts of the original part, the parent of the original part, and the children of the parent of the original part. Two parts are then selected from this list at random, and then 67% of the original post-armor damage is dealt to both parts. This damage may be limited by overkill prevention however. 

Overkill prevention works as follows: If the damage would be insufficient to reduce the HP of the body part in question, full damage is dealt. If the damage would be sufficient, two outcomes are possible - either the part is destroyed or the part is reduced to 1 HP. First, the amount of damage over the current HP of the part is determined. This is then divided by the maximum health of the body part when completely healthy. This is the "Overkill Percentage". This overkill percentage is then compared to the "overkillPctToDestroyPart" range unique to the damage type. In this instance, Scratch has a range of 0~0.7, or 0 to 70%. An inverse lerp is then performed using the Overkill Percentage and this range. 

{| class="wikitable"
|-
| Chance to Destroy = (OVERKILL PERCENTAGE - LOWER)/(UPPER - LOWER) 
|}

This result is the chance that the body part is destroyed by the attack. For example, if the attack deals 70% of the parts maximum health as Scratch Type Overkill Damage, then there is a 100% chance the body part would be destroyed. If the chance is failed, the part is not destroyed and instead reduced to 1 HP.

==Toxic bite==
Identical to [[#Bite|Bite]], but inflicts a 1.5% severity increase of [[toxic buildup]] for each point of Bite damage inflicted, multiplied by the [[Toxic Sensitivity]] of the target.

Animals will not apply the toxic buildup hediff when hunting for food, even when using an attack with this damage type. This is to prevent them from rotting their prey with toxic buildup, and being left unable to eat, only to have to repeat the cycle.

==Thump==
Thump damage is done by [[Thump cannon]], and is exceptionally effective against buildings. The default damage is only 5, with 0 AP, however it does 4x Damage to Plants, 15x damage to impassable buildings such as Nutrient Paste Dispensers, 7.5x to passable buildings such as armchairs. Additionally, both [[wall]]s and natural rock walls specifically have an additional 2x multiplier, stacking with the previous 15x, for a total of 30x damage.

==Version history==
* Beta 19/1.0 - Bomb damage now does 2x damage vs plants. '''Note:''' this was increased in a later version to 4x, as noted above.
* [[Version/1.3.3200|1.3.3200]] - thump damage multiplier versus [[wall]]s reduced from 4x to 2x.
