4th ring Arcane, Illusion
You tap into the nightmares of a creature you can see within range and create an illusory manifestation of its deepest fears, visible only to that creature. The target must make a WIS save. On a failed save, the target becomes frightened of you for the duration. At the end of each of the target’s turns before the spell ends, the target must succeed on a WIS save or take 4d10 psychic damage. On a successful save, the spell ends.
