Time Rewind

Immediately after a creature's turn, you rewind the fabric of time itself.  Time reverses to the end of your last turn. Everything that happened following your last turn is erased. You then can take a turn to attempt to change the outcome as if it were a new round of combat. Once you have taken this turn, the initiative starts again. A creature can use the same actions and outcomes without rerolling or choose to make different actions and new rolls (they must take any new rolls if they make them). Additionally, you can influence any creature within range, awarding Advantage or Disadvantage to one action, bonus action, reaction or saving throw to each creature, including yourself until the start of your next turn.
