Visions of Madness

You instill horrifying visions in the mind of an enemy you can see within 60 feet. The target takes 2d6 + your spellcasting ability bonus psychic damage at the end of each of their turns, and must then make an Intelligence saving throw. On a success, the spell ends. If the target cannot be affected by illusions, they take half as much damage and suffer no further effects. If the target dies while affected by this spell, the nearest enemy within 30 feet becomes affected by it.
