Time Prevents All

You touch a creature and heal them by 3d10 hit points as you rewind that part of their body to a state it looked before they took damage.

This is not a simple healing spell though, as the creature still remembers and feels a phantom pain, the effected creature must roll 1d10 and on a 2 or lower they suffer from on level of exhaustion.

The injury sustained must've been withn 24 hours of receiving the wound otherwise the spell has no effect. 

The HP healed by this spell increases with 1d10 with every level spell slot used higher.
