The Shroud of Truth

Wondrous item, legendary (requires attunement by a lawful evil character)

The Prince of Darkness amuses himself with half-truths, innuendo, and the small lies that murder some part of the world. The irony of naming this gift to mortals the shroud of truth was not lost upon him.

A yellowish brimstone smoke rises from the edges of this red and black velvet cape. The cape itself is lawful evil and deals 14 (4d6) necrotic damage per round to any non-lawful evil entity who attempts to handle it.

Wearing this cape grants you +3 to your armor class and a +2 to your Charisma score as well as the ability to cast charm person and disguise self at will with a spell save DC of 18.
