Unmake Life

To cast this spell, the castor must wound himself using a slashing weapon. The castor takes the weapon's damage, as well as 5d6 necrotic damage in the process. The spell fails if this drains the castor to 0 hp. If successful, the castor chooses a single LIVING target he can see within 300 feet. This spell is then released from the castor's hand in a flash of light, and all creatures within 30 feet must make constitution saving throws. On a failed save, the creatures take 5d6 radiant damage, plus 3 times the amount of hp the castor lost at the time of casting in psychic damage. The creatures take half damage on a successful save. The target of the spell must make a dexterity saving throw, and takes 50d8 force damage plus 10 times the amount of up lost by the castor in psychic damage on a failed save, or half as much on a successful one. If this reduces the target to 0 hp, it is removed from existence without a trace, and can only be brought back by a wish spell or similarly powerful magic.
