For the duration, you have advantage on all Charisma checks directed at one creature of your choice that isn't hostile toward you. When the spell ends, the creature realizes that you used magic to influence its mood and becomes hostile toward you. A creature prone to violence might attack you. Another creature might seek retribution in other ways (at the DM's discretion), depending on the nature of your interaction with it.
You unleash a string of insults laced with subtle enchantments at a creature you can see within range. If the target can hear you (thought it need not understand you), it must succeed on a Wisdom saving throw or take 1d4 psychic damage and have disadvantage on the next attack roll it makes before the end of its next turn.
This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4) and 17th level (4d4).
