Vicious Moggery

You flex your masseter muscles, tilt your head downwards, and strike a subtle pose, exposing the full extent of your aesthetics. If the target can see you, it must succeed on a Charisma saving throw or take 1d4 psychic damage and have disadvantage on the next attack roll it makes before the end of its next turn.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
