As an action, you unleash a string of insults laced with subtle enchantments at a creature within 18 meters. If the target can hear you (though it need not understand you), it must succeed on a Will saving throw or take 1d4 psychic damage and it 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 1d4 when you reach 5th level (2d4), 9th level (3d4), 13th level (4d4), and 17th level (5d4).
