Curse items

Curse items is one of the most despicable monster spells in NetHack. It is usually casted by a lich. This spell will curse up to six random items in your inventory if it succeeds; blessed items will become uncursed and uncursed items will become cursed. If you have half spell damage or magic resistance, the number of items cursed is capped at three; if you have both, the number is capped at two.

Intelligent artifacts will resist the curse 80% of the time; Magicbane will abosrb the curse harmlessly 95% of the time.

Some random inventory items were cursed.

"You feel a malignant aura surround the magic-absorbing blade."

Magicbane, when wielded, has a 95% chance of harmlessly absorbing the curse, producing no ill effects.
