Time Flux

You briefly reverse the flow of time for everyone but yourself...

This spell reverses the flow of time for everyone in a 50-foot-radius, 100- foot high cylinder centered on the caster. All creatures and objects, that aren't somehow immune to the affect, revert back 1d4+1 rounds. Damage, conditions and all other effects are returned to their previous state from 1d4+1 rounds ago. All creatures and objects return to their location from 1d4+1 rounds ago. All affected creatures retain their memory of the altered timeline, as if 

Note: This spell cannot bring someone back from the dead, unless their soul was somehow trapped within the limits of the spells Area of Effect. Their soul would have moved on, however; their body would be returned to it's previous location and healed.
