Vicious Mockery

0-level (Cantrip) Enchantment

You unleash a string 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 1d4 1d4 psychic damage and have disadvantage on the next Attack roll it makes before the end of its next turn.
 
At higher levels: This spell's damage increases by 1d4 when you reach 5th level (2d4) 2d4 , 11th level (3d4) 3d4 , and 17th level (4d4) 4d4 .
