Terrifying Lash

A faintly luminous whip of energy coalesces in your hand. The whip has reach, and you can take an action to make a melee attack roll against a target on your turn, using your spellcasting ability modifier as a bonus on the attack roll. On a hit, the target takes 2d10 psychic damage and must make a Wisdom saving throw. On a failed save, the target is frightened for 1d4 rounds. If you attack a target with this spell that is already frightened, you gain advantage on the attack roll, and the target has disadvantage on its Wisdom saving throw.
