Travelyan's Unrelenting Mockery

You unleash a torrent of insults laced with subtle enchantments at a creature you can see within range. If the target can hear you (though it need not understand you), it must succeed on a Wisdom saving throw or take 2d8 psychic damage (plus your spellcasting modifier) and have disadvantage on the next attack roll it makes before the end of its next turn.

When you cast this spell using a spell slot of 3rd or higher, the damage increases by 1d8 for each slot above 2nd.
