Cheers

You raise your cup to one creature you see within range who can also see you. The target must succeed on a Wisdom saving throw or immediately use its reaction to cheer you back, and take 1d4 psychic damage in the form of embarrassment and/or shame for falling for such a trick. If the target does not have an available reaction, the spell has no effect. 

At Higher Levels. The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4), and 20th level (5d4).
