Thunder Note

You emit a crashing bang at the location of a creature you can see within range. The target must succeed on a Constitution saving throw or take 1d8 thunder damage and become deafened until the start of its next turn.

If this damage forces it to make a Constitution saving throw to maintain concentration on a spell, it makes that save at disadvantage.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
