Mirror of Time Hop: This small hand mirror manifests its power up to twice per day against creatures that see their reflections 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 14 Will save or be pushed forward in time by 5 rounds, as if subject to the time hop power. Because the mirror is small, only a single creature can meet its own gaze each round. The wielder of the mirror is not affected by seeing herself.
