Spread carnage and corruption!
Henzell says...
  1. Damage from "You are splashed with acid!" is an extra 4d3, reduced by 50% by {rcorr}. May inflict {corrosion} status, reducing your AC and slaying. Monsters only take 2d4, since they're dirty cheaters.
  2. Prior to 0.27, ranged acid attacks (like oklobs) did 4d5 bonus acid damage on top of the displayed damage. Prior to 0.17, damage decreased with equipped armour slots.
