Test the Body

Choose a creature within range that will be tested as you bellow holy incantations of divine judgment. The material component for this spell vanishes and is replaced with a floating, spectral book above the target of this spell. The target makes three saving throws, one strength, one dexterity, and one constitution. For each failed saving throw, the target takes 4d12 lightning or radiant damage (your choice) as blots of lightning streak down from the sky. A creature that fails all three saving throws does not suffer damage from these bolts, they are instead found wanting. You may choose to forgo the found wanting effect and instead deal 12d12 damage of any type to the target creature. 

A creature that is found wanting is cursed by divine powers for 1 day, as the body it once had is altered to reflect the wanting body that it truly is. A wanting creature cannot regain hit points except by magical means. And it's strength, dexterity, and constitution become 10 unless they were already lower. Also, a wanting creature is not proficient in saving throws or skills that use these ability scores.
