Mirror of Mind Switch: This small hand mirror manifests its power once per day against a creature that sees its reflection within it, as a gaze attack with a range of 30 feet. Potential victims can attempt to avert their eyes or look away as they would from a normal gaze attack. A creature meeting its own gaze in the mirror must succeed on a DC 19 Will save, or its mind and the mind of the mirror’s wielder switch, as if by the mind switch power. Because the mirror is small, only a single creature can meet its own gaze. The wielder of the mirror is not affected by seeing himself.
