Disorder Eye

You send a mental barrage towards a creature you can see, filling their vision with illusory copies of yourself. Until the end of your turn, you have advantage on attack rolls against that creature, and the first time you hit with an attack after casting this spell, the target takes an additional 2d8 psychic damage.

At higher levels. When cast using a spell slot of 3rd level or higher, the target cannot benefit from half-cover or three-quarters cover on your turn.
