Clock Magic: Self Time Reversal

This spell controls the time that has affected your body for the last 6 seconds. As a reaction to anything finishing an action you can return back in time 6 seconds, returning you to your original position and reversing any damage that you took during that turn. This does not return uses/ used charges of items or abilities. If before you cast this spell, in the affected amount of time, you took damage equal to a quarter of your maximum hit points or larger,  then your body enters shock and is unable to cast this spell.

At Higher Levels. Every 2 levels added to this spell will increase the time by 6 seconds. (Ex. Spell at 4th level affects last 12 seconds, spell at 6th affects last 18 seconds.)
