Crucio

Although an excellent tool for interrogation, the Cruciatus Curse is one of the most terribly powerful and sinister spells known to Wizardkind. When cast successfully the curse inflicts intense, excruciating pain on the victim. Considering that the spell does not physically harm the victim, it is possible that it only stimulates pain receptors, therefore, the target takes 1d8 of Psychic DPR. The target cannot fight back, nor can it escape its painful grasp. If the target's Hit Points reach zero, their heart stops and they die from the insane shock of pain. The target can only make a Dexterity saving throw when they are first targeted by this curse. If they fail, their only hope for survival lies on someone attacking the caster--or the release of the spell.
