Chronal Recovery

Time is a weird soup and your understanding of the concept has garnered insight on the impact it has on the human (or not) body. You may use your intellect to reverse the effect and passage of time. 

Select one creature, or yourself, that you can see within 30ft. Using your knowledge of chronology you can reverse the effect time has had on them by 1 hour per spell level spent. Creatures effected in this way recovery all hit points, spell slots, levels of exhaustion or any other effect the DM chooses. Spell slots spent on this feature cannot be recovered in this way. 

You can gain 1 level of exhaustion to target a 2nd creature. 

This feat is restricted to Wizards with the chronomancer sub class
