Thunderous Vocals

You scream a verse of a song at a magically enhanced volume, causing thunderous energy to assault your enemies. Each creature of your choice within range that can hear you must make a Constitution saving throw. On a failed save, a creature takes 4d6 thunder damage and is pushed 10 feet away from you. On a successful save, the creature takes half damage and isn't pushed.

Additionally, any unsecured objects within the spell's range are automatically pushed 10 feet away from you, and the spell is audible out to a range of 300 feet.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
