 +
* The same player wielding a +0 rapier with a base damage of 8 can do up to 13 damage.
 +
 
 +
So, the stat and skill bonuses increase the dagger's damage by 25% and the rapier's damage by 62%. The dagger would deal up to 10 damage per 10 [[aut]], while the rapier would deal up to 20. For this player, a +5 dagger would be inferior to a +0 rapier (if not used for [[stab]]bing).

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

Weapon damage is your base weapon damage, multiplied by strength modifier, multiplied by weapon skill and fighting skill modifiers. Slaying bonuses and weapon enchantment are added afterwards. Actual damage components are randomly rolled in four places: 1d(Base * Strength modifier), Slaying bonus, Weapon skill modifier and Fighting modifier.

Damage formula

Damage = [uniform(Base damage * Stat modifier) * Skill modifier * Fighting modifier + Misc modifiers + uniform(Slaying bonuses)] * final multipliers + Stabbing bonus - AC damage reduction[1]

  • While final multipliers are applied after stabbing bonus, the stabbing bonus doesn't benefit from these multipliers.

As a shorthand uniform(x) = 1d(x+1)-1 or a roll from 0 to x inclusive.

Notes

  • The main contributions to weapon damage are: base damage, weapon skill (avg. +54% at level 27) and fighting skill (avg. +45% at level 27).
  • At low skill values, 1 base damage roughly equals +1 slay. As you gain skill, only base damage is multiplied, resulting in a greater effect. 1 base damage = 1 + (average of Stat mod * Skill mod * Fight mod) slaying.
  • When weapon damage is viewed in the 'i'nventory or with the @ command, the "Skill" bonus is Skill mod * Fighting mod, using the average of both rolls.
  • Weapon brands (except heavy) are applied at the end of the formula, after AC reduction. The added damage then ignores AC.
In other words, the flaming or freezing brands aren't any better on an executioner's axe than on a quickblade. For example, if a +0 axe and +9 quickblade dealt the same damage per turn, a +0 axe of flaming and +9 quickblade of flaming would also deal the same damage per turn.

Rounding

Each term in the formula is calculated in sequence and is rounded down to an integer. This rounding is worse with a weapon with low base damage. For example, take a player with Dex = 12 and Short Blades skill = 12:

  • With no slaying bonuses, a +0 dagger with a base damage of 4 cannot do more than 5 damage.
  • The same player wielding a +0 rapier with a base damage of 8 can do up to 13 damage.

So, the stat and skill bonuses increase the dagger's damage by 25% and the rapier's damage by 62%. The dagger would deal up to 10 damage per 10 aut, while the rapier would deal up to 20. For this player, a +5 dagger would be inferior to a +0 rapier (if not used for stabbing).

History

  • In 0.29, launcher, long blade, and short blade damage now scale with dexterity instead of strength.
  • In 0.27, the strength modifier was simplified and made nonrandom.
  • Prior to 0.18, weapons used a mix of strength and dexterity, depending on the weapon itself.
  • Prior to 0.13, stats had half the effect on melee.
  • Between 0.8 and 0.13, melee weapons of speed suffered a -10% penalty to damage.
