Perish

9-level Evocation (ritual)

The user sacrifices all but 1 of their hit points to hit a single enemy within sight with 100d100 of soul damage. This spell takes up 1 9th level spell slot and two other spell slots from any level.   The target will have the chance to roll 1d20. On a natural 20 roll, the target soul suppresses the attack and the user still uses the 3 spell slots and is brought to 1 health.   If the target does not have a soul, the spell fails.
