Undo

By using the powers of necromancy to reverse pain inflicted upon others, you can choose a target within range and have their hit points revert to what they were last round, regardless if the amount is higher or lower than their current hit points. This can also be used to resuscitate an unconscious creature by undoing the damage that took them down. If a creature is unwillingly targeted by this spell, they will have to attempt a Constitution save to avoid the spell's effects. This spell cannot bring a dead creature back to life, and cannot affect temporary hit points.
