Discordant Sound

You play a short, discordant, and abrasive melody, magically focusing the sound on one creature within range. If the attack hits, it deals 2d8 Thunder damage and the target has Disadvantage on its next save to maintain concentration on a spell until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd. You can also target one additional creature within 20' of the original target for every 2 slot levels above 2nd.
