Chronal Backstep

As a bonus action, you can teleport back to where you started at the beginning of this turn and reverse all damage you’ve taken since the start of this turn.  Any damage or effects dealt to enemies in this turn by you remains. (If your DM doesn’t trust you to record damage on yourself for this round, you have the responsibility to let them know you are considering this spell at the start of any round you plan to use it).  Outside of combat, this does the same thing but delivering you 6 seconds back.
