Weapon Damage

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

Math

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

Sources
