The scroll of destroy armor selects a random piece of worn armor and destroys it. If the scroll is cursed and targets cursed armor, it will not destroy the armor, but instead lower its enchantment by one. If the cursed armor is -7, there is no effect except you become stunned for 10-19 turns. If a non cursed scroll of destroy armor is read while confused, it will instead remove erodeproofing from a random piece of worn armor (if any). If a cursed scroll of destroy armor is read while confused, it will make a random piece of equipped armor erodeproof.
