Cheers

You raise your glass to one creature you can 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 creature doesn’t have an available reaction or if its intelligence is less than 4, the spell has no effect.

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