Condemnation

You attempt to invoke the authority of greater powers to mark a creature's soul for eternal damnation in the lower planes. Choose a creature you can see within reach. That creature must make a Charisma saving throw, taking 10d10 fire damage, 10d10 psychic damage, and 10d10 radiant damage on a failed save, or half as much on a success. If a creature that has a soul (such as a human, elf, or goblin) that fails its save dies within 24 hours, its soul is instantly condemned to one of the lower planes, such as the Nine Hells or Carceri (your choice). A creature condemned this way cannot be resurrected by any means other than a wish spell.

Once you cast this spell, you cannot cast it again for 1 week without gaining 2 levels of exhaustion.
