Galiforme Island

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 wisdom saving throw. On a failed save, the target becomes frightened for the duration. At the start of each of the target's turns before the spell ends, the target must succeed on a wisdom saving throw or take 4d10 psychic damage. On a successful save, the spell ends.
