Vicious Retort

As you shrug off the insult from the vicious mockery spell, you unleash an enchanted retort against the creature that cast the spell. The target must succeed on a Wisdom saving throw or take 1d6 Psychic damage and have Disadvantage on the next attack roll it makes before the end of its next turn.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
