Truth Brand

Effect: A piece of void-glass chalk. When used to mark a creature (touch required or markings made on a surface they step through), leaves a brand visible only through Void Glass, Truesight (see invisible creatures and through illusion), or equivalent perception. The brand marks every lie the branded creature tells for 24 hours with a visible flare of red light. The creature is not aware of the brand or when it flares. Fades naturally after 24 hours.
Uses: One use per piece. Found 1d4 pieces at a time.
