Earworm

A small pink bolt shoots from your finger, filling the target's head with the most irritating melody they know. On a successful hit, the target must make a Wisdom saving throw. On a failed save, the target's head is filled with the most irritatingly catchy song known across the land, giving them Disadvantage on attack rolls. The target also takes 1D4 psychic Damage. These effects repeats every combat turn, until the target succeeds the saving throw.

The damage increases to 2D4 at 5th level, 3D4 at 10th level, and 4D4 at 16th level.
