--[[ Version 2.4 Last updated 19/1/2026 Damage formula: baseDmg(1 + ∑additive_buffs) * (1 + ∏multiplicative_buffs) Additive buffs are first calculated, via (1 + buff1% + buff2% + buff3%) etc, THEN multiplicative buffs via (1+buff1%)(1+buff2%)(1+buff3%) Copy & Paste this into any online Lua run website and it should work, or press the funny green button > fork on this website
