Beating Rhythm

 When you cast this spell, the Target takes 1D6 Thunder damage as all they can hear is a loud beating on a drum so loud it makes their ears bleed, they must make a Wisdom saving throw or have disadvantage on all, ability checks, saving throws, and attack rolls while you are concentrated on this spell.

 It becomes 2D6 at level 6, 3D6 at level 12, and 3D8 at level 17.
