Blunt

If a strike from an attack dealing blunt damage is sufficient to destroy the struck 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 humans and most other pawns, there is a small chance to 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 humans and most other pawns, there is a larger chance to 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 a default AP of 10% and 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, Walls specifically have an additional 2x multiplier, stacking with the previous 4x, for a total of 8x damage.

Burn

Identical to Flame except that it cannot ignite targets.

Demolish

Demolish damage is done by breach axes and is additionally effective against buildings. It applies a 10x Damage multiplier when attacking buildings, but applies an additional 0.75x multiplier when attacking the target is impassible such as walls, for a net multiplier of 7.5x against that class of building. In all other ways, it is otherwise identical to Blunt damage.

EMP

EMP damage is a fairly unique form of damage that does no direct harm to organic pawns, but temporarily stuns mechanical pawns and some objects.

The weapons that deal EMP damage include:

Additionally, when destroyed the Defoliator condition causer will release a EMP blast with a 9 tile radius.

EMP mainly serves to stun mechanoids, turrets, and mortars. Every stun "damage" inflicts 30 ticks (0.5 secs) of stun. Most items do 50 EMP damage, or 25 seconds of stun.

After being stunned, mechanoids become 'Adapted', gaining immunity from further stuns for 2,200 ticks (36.67 secs). The immunity starts ticking down as soon as the stun is applied; stun duration or future stuns have no effect on adaptation. The post-stun Adapted duration is 700 ticks (11.67 secs) for most items. Some mechanoids in the Biotech DLC Content added by the Biotech DLC have EMP resistance, so are stunned for less time.

Damage Sources Stun Duration Post-Stun Adaption Duration Ideal Stun Uptime
9 Zeushammer, Persona zeushammer 270 ticks (4.5 secs) 1,930 ticks (32.17 secs) 12.27%
45 Awful quality EMP launcher 1,350 ticks (22.5 secs) 850 ticks (14.17 secs) 61.36%
50 All other sources 1,500 ticks (25 secs) 700 ticks (11.67 secs) 68.18%
62.5 Masterwork quality EMP launcher 1,875 ticks (31.25 secs) 325 ticks (5.42 secs) 85.23%
75 Legendary quality EMP launcher 2,250 ticks (37.5 secs) ticks (0 secs) 100%

Any amount of EMP damage will also:

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

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 protective apparel, there is a chance to 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:

Ignition Chance per Target Flammability

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.

In addition to weapons that deal flame damage, lightning also deals 10 flame damage its area of effect.

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.

For example, a power claw deals Attack 1 Damage scratch damage. If the initial attack targets the nose, the head's child part, then the two eyes could be selected as they are also child parts of the head. If the initial attack was also halved by armor, then this attack would deal 11 damage to the nose and 7.37 to each eye.

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.

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, but also inflicts a 1.5% severity increase of toxic buildup for each point of Bite damage inflicted, multiplied by the Toxic Resistance of the target and inversely proportional to the body size of the target i.e. a target with 50% Toxic Resistance and a body size of 2 will take 25% of the toxic buildup.

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.[Wildmen?]

Toxic bullet

Identical to Bullet, but also inflicts a 0.65% severity increase of toxic buildup for each point of Bullet damage inflicted, multiplied by the Toxic Resistance of the target and inversely proportional to the body size of the target i.e. a target with 50% Toxic Resistance and a body size of 2 will take 25% of the toxic buildup.

The tag is set such that animals will not apply the toxic buildup hediff when hunting for food, even when using an attack with this damage type, however it is unclear if this is functional or merely a hold over from copying the standard set by toxic bite as that condition cannot occur in vanilla. It is also unclear whether it would apply to colonists hunting with such weapons.[Verify]

Toxic scratch

Identical to Scratch, but inflicts a 1.5% severity increase of toxic buildup for each point of Scratch damage inflicted, multiplied by the Toxic Resistance of the target and inversely proportional to the body size of the target i.e. a target with 50% Toxic Resistance and a body size of 2 will take 25% of the toxic buildup.

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 walls and natural rock walls specifically have an additional 2x multiplier, stacking with the previous 15x, for a total of 30x damage.

Vaporize

Vaporize damage is done by the hellsphere cannon. The default damage is 800, with a default AP of 100% and stopping power of 1.5. It does 4x to impassable buildings such as Nutrient Paste Dispensers, 2x to Plants and passable buildings such as armchairs, and 0.1x damage to corpses.

It is resisted by heat armor and heats up the area in which it is fired.[Detail needed]
