The Great Clock Rewinds

The Caster connects to the energy created by the flow of time throughout the multiverse.  When cast, time rewinds 6 seconds in a 200 ft sphere, centered on the caster, undoing all actions and effects of the caster choice within the affected area.  If in initiative the caster regains his action and can take it immediately. Only the caster retains knowledge of the events that occur during the time period.
