Darktide has an intricate system with many knobs to tune damage.


Among those knobs are:


All sources of rending_multiplier are additive.


Here’s a reference for various terms used in this doc:


Rending is sometimes thought to scale to Unarmoured damage.

This is inaccurate since Unarmoured damage is itself the product of base damage, armor_damage_modifier, and rending_multiplier.


rending_multiplier is multiplied by 1.0 - armor_damage_modifier.

When armor_damage_modifier is less than 1.0 it will increase damage.

When armor_damage_modifier is greater than 1.0 it will decrease damage (an acknowledged bug).


For example, a damage increase case:

rending_multiplier = 0.2 (20% Rending/Brittleness)
armor_damage_modifier = 0.6

difference = 1.0 - armor_damage_modifier
  = 1.0 - 0.6
  = 0.4

rending = difference * rending_multiplier
  = 0.4 * 0.2
  = 0.08

final_damage_multiplier = armor_damage_modifier + rending
  = 0.6 + 0.08
  = 0.68 (13.3% increase in damage)

and a damage decrease case:

rending_multiplier = 0.2 (20% Rending/Brittleness)
armor_damage_modifier = 1.8

difference = 1.0 - armor_damage_modifier
  = 1.0 - 1.8
  = -0.8

rending = difference * rending_multiplier
  = -0.8 * 0.2
  = -0.16

final_damage_multiplier = armor_damage_modifier + rending
  = 1.8 - 0.16
  = 1.64 (9% decrease in damage)

The value of a hit’s armor_damage_modifier is based on:

  1. charge (helbore, plasma gun, etc)
  2. distance (any range weapons)
  3. armor modifier for armor type
  4. crit_mod on crit if it exists for that armor type

Range stat scales dropoff start and end when interpolating near and far armor modifiers.

Some stats scale armor modifier.

Critical stat scales crit_mod if the hit has it.


For melee weapons charge and distance (1. and 2.) are not used.


For multi-hit attacks the armor_damage_modifiers are estimated from all hits.


Some attacks, like flamethrower, are not included due to lack of support.



rending_multiplier is also used in stagger calculations.

If rending_multiplier is greater than 0 for a hit then:

stagger_strength = stagger_strength * 2 * rending_multiplier

Note that when rending_multiplier is less than 0.5 it’ll reduce stagger_strength:

rending_multiplier = 0.2

stagger_strength = stagger_strength * 2 * rending_multiplier
  = stagger_strength * 2 * 0.2
  = stagger_strength * 0.4 (60% less stagger strength)

This is an acknowledged bug.



Weapons and Attacks

This list is intended to be used for determining how effective rending_multiplier is on a given weapon.


It is ordered:

  1. per weapon
  2. per attack
  3. per stat*
  4. per armor
  5. per hit (base, crit, or both)

*Along with the weapon stats are “flat” and “all 80% stat”:


Hits are formatted either as:

Which is a fixed armor_damage_modifier value that is modified by no stat.


or as:

Which is the armor_damage_modifier value with the stat at 0%-80% respectively.


hit is:

  1. base for a non-critical hit.
  2. crit for a critical hit.
  3. both for both non-critical and critical hits.
