Youngblood

You perform a refreshing hour-long ritual on a conscious creature that gives them temporary hit points equal to half their maximum hit points, restores all spell slots of 3rd level and below, and heals them of any curable ailments.

Upon casting Youngblood on a creature, you may also attempt to revert its mental age to 24 hours in the past, erasing any memories made in that period of time and reverting their mental structure to what it was before. If the creature's mind is unwilling, it may make a Charisma saving throw to avoid mental reversion. Unconscious creatures can also be reverted and automatically fail their save, though creatures who have died or creatures younger than 24 hours cannot be reverted.
