Credit to Whyu1nunno Base Damage (Base Power + Modifiers) / (1 + Armor/100)
(800 + (120% of Base Attack power [removed natural 99 wp from here])) / (1+170/100))
1196/2.7=442.96 base damage vs Metal jacket (without pierce)

Pierced Damage = %Pierced*(Basic Attack) + (1-%Pierced)*Basic Attack/(1 + Armor/100)
(80%*(1196)) + (1-.80)*1196/(1 + 170/100)
956.8+ 88.59 = 1045.39 damage with 4x tension bow and sorrowblade

Do passives stack? Or is it just the stat increases that do? If the passives stack then holy **** this is OP.

This build shouldn't work but it does. Bug repot has been submitted a couple weeks ago. 1.12
