Temporal Shunt

When a creature within range makes an attack or uses a power, the triggering creature must make a WIS save or vanish until the start of its next turn, causing the triggering attack or power to have no effect. It reappears in its space or the nearest unoccupied space.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
