9-level Enchantment
You put your hand on a target’s head and attempt to warp their mind into only the fear of life and living. The target must make a Wisdom saving throw or fall unconscious, trapped in their own mind until they die. Only a wish spell can remedy this coma. If the target dies while under this effect and if it has a soul, its soul is similarly trapped in an endless cycle of fearing life, caught between this world and the next, and not willing to be resurrected.
