Weapon DamageGive feedback

Weapon Damage is a stat that determines the player's Bullet Damage, and also increases their Melee Damage. Some abilities can deal Weapon Damage.

Video explaining Weapon Damage

Base Weapon Properties

Base Bullet Damage

Base Bullet Damage is the amount of damage your Hero deals with no items. This value is unique to each hero and increases automatically as you level up through Boons.

Spreadshots

Spreadshots allow certain weapons to fire multiple bullets at once (such as shotguns or shurikens). In these cases, all calculation rules apply to every individual bullet.

Drifter Is an exception to this, where the same amount of bullet damage is dealt to a target regardless of how many pellets hit per shot.

Piercing shots

Paige's weapon's shots pierce through enemies and can hit multiple enemies per projectile, disappearing only when they hit a map surface. However, they do not deal headshot bonus damage, but can proc headshot items.

The Doorman's weapon's shots also pierce enemies. Unlike Paige's, they can deal headshot damage but deal half damage to all enemies hit after the first.

Melee Damage

Melee Damage is considered a source of Weapon Damage and scales with the Weapon Damage stat by 50%. Items and abilities that trigger from "dealing weapon damage" or "weapon damage hits" (e.g. Stalker, Card Trick, etc.) include Melee Damage. Some effects that specify "bullets", such as Metal Skin and Toxic Bullets, have no effect with Melee Damage, but others do (such as Slowing Bullets and Weighted Shots).

In addition to Melee Resist gained from items, Bullet Resist affects all Weapon Damage, granting another source of resistance against Melee Damage. The only exception is Venator's innate Spirit-scaled Bullet Resist, although this is likely a bug.

Combat Modifiers

Damage Falloff

Damage Falloff reduces damage based on distance. All heroes have a Falloff Range in which damage is linearly reduced from 100% to 10%.

When aiming at an enemy hero, a dot on their health bar indicates the percentage of damage you will deal:

Dot Color	Damage Percentage
Red	10% - 20%
Orange	20% - 35%
Yellow	35% - 75%
Transparent	75% - 100%

Crit Multiplier

Aiming for the head deals increased damage. Troopers, Guardians, and Heroes have a weakpoint hitbox that receives 1.65x bullet damage when hit.

$Crit Multiplier = 1 + [(0.65 + Crit Bonus Scale) \times Crit Resist]$

The following heroes cannot deal critical damage:

Graves
Paige (though she can proc headshot item effects)
Viscous' alt-fire
Yamato's alt-fire

Crit Bonus Scale is a stat that modifies critical damage dealt by certain heroes.

Base Crit Bonus Scale Stats
Hero	Crit Bonus Scale (%)
Billy	-20
Celeste	-25
The Doorman	-30
Drifter	-45
Kelvin	-25
Rem	-20
Vyper	-30

Abilities that can deal critical damage have different critical modifiers. This replaces the +65% multiplier of base weapons.

Ability Crit Damage Stats
Hero	Ability	Crit Damage (%)
Paradox	Kinetic Carbine	14
Venator	Ira Domini	30
Vindicta	Assassinate	20

Target Modifiers

Bullet Resistance

Main article: Damage Resistance

Incoming damage is reduced by the target's Bullet Resist and increased by the attacker's Bullet Resist Reduction. These stats stack multiplicatively. For a detailed breakdown on how multiple items stack, see the main page.

Increased Bullet Damage

Increased Bullet Damage is a debuff inflicted on enemies. It multiplies the total amount of damage they take from you. Because this is applied at the end of the calculation, it also increases the effectiveness of your Flat Weapon Damage.

Flat Weapon Damage

Flat Weapon Damage is an extra amount of damage obtained through certain hero abilities.

Flat Weapon Damage is not increased by your "Weapon Damage %" multiplier. It is an additive source added to your total after the percentage multiplier is applied to your base. However, it is still affected by Damage Falloff, Bullet Resist, and Crit Multipliers.

Weapon Damage Formula

The final damage dealt by a bullet is determined by multiplying your base stats, your item bonuses, and various situational modifiers.

$\begin{matrix} Final Damage = \\ [(Base DMG \times DMG Multiplier) + Flat Bonus] \\ \times Falloff \times Resistances \times Crit Multiplier \end{matrix}$

Weapon Damage Scaling

Some abilities scale with Weapon Damage.

For most Weapon Damage scaling abilities, they only scale based on the "Bonus Weapon Damage" stat, which is granted by items and Weapon shop investments (see list below). Paradox's Kinetic Carbine is an exception, since it scales with her Base Weapon Damage (counting as a full burst shot), and thus increases with Boons. Melee Damage scaling abilities also scale with Weapon Damage, since Melee Damage scales with Weapon Damage (by 50%).
