As an action, you unleash a string of insults laced with subtle enchantments at a creature within 5 meters. If the target can hear you (though it need not understand you), it must succeed on a Will saving throw or it takes 1d6 psychic damage and has disadvantage on the next attack roll it makes before the end of its next turn.
On a successful save, it takes half as much damage and doesn’t suffer disadvantage.
At higher levels
This spell’s damage increases by 1d6 when you reach 9th level (2d6) and 17th level (3d6).
