Monstrous Mask (Patreon)

Wondrous item, rare

This painted wood mask weighs 3 pounds and resembles a mish-mash of various roaring monsters. While wearing it, you can use an action to cast the polymorph spell on yourself from the mask. You transform into a random monstrosity, instead of a beast. When you do, you retain your Intelligence, Wisdom, and Charisma scores. Roll a d6 and consult the table below to determine which monstrosity you transform into:

For the duration of the spell, you can't be frightened, and you have advantage on Constitution saving throws made to maintain concentration on the spell. Once this property of the mask has been used, it can't be used again until the next dusk.

"Alright, listen, I know you're new to the banditry lifestyle, but 'trick or treat' is not a substitute for 'your money or your life'."
