Weapon Damage

Weapon Damage is a stat that increases Bullet Damage, Light Melee Damage, and Heavy Melee Damage.

Headshots

Aiming for the head will deal increased damage. Troopers, Guardians, and Heroes have a weakpoint hitbox that receives approximately double base bullet damage when hit by a weapon. Seven receives reduced incoming headshot damage.

Several items have effects that proc on headshots, such as Headshot Booster, Headhunter, and Crippling Headshot.

Math

The formula for weapon damage is: $x_f=x_i\ast (1+\sum _{i=1}^n\text{Shop Bonus}+\sum _{i=1}^n\text{BaseAttackDamagePercent}+\sum _{i=1}^n\text{Golden Statues})$
where:
$\begin{array}{cc}{x}_f& =\text{final weapon damage,}\\ x_i& =\text{initial weapon damage,}\\ ShopBonus& =\text{Increase based on the tier,}\\ BaseAttackDamagePercent& =\text{weapon damage value,}\\ GoldenStatues& =\text{Golden Statue value}\end{array}$
