Raccoon Mask of Comical Banditry (5e Equipment)
From D&D Wiki
Wondrous item, rare (requires attunement from a rogue)
A small black mask that fits over the eyes.
Cunning Disguise. The mask somehow manages to disguise the wearer, preventing anyone from recognizing them unless they are looking at the user when they put it on.
Curse. The user is constantly gripped by crippling greed. Whenever they see any money or valuables worth at least 100 gp, they must succeed on a DC 15 Wisdom saving throws. If they succeed nothing, happens. If not, they must attempt to steal the treasure or suffer disadvantage on all Charisma, Intelligence, and Wisdom until they attempt to steal from valuables. If the wearer willingly plans to rob a location, they must attempt to do so in the most unusual matter conceivable.
