Bass drop

A wave of pure sound explodes from you. Every creature within a 30 foot-diameter sphere centered on you must make a Dexterity saving throw. On a fail, the creature takes 1d10 thunder damage and is pushed to the edge of the sphere. If this results in the creature being pushed more than 5 feet, they are also knocked prone. At the start of your turn(until your concentration ends) the effect above is repeated.

At Higher Levels. For every spell level above 1st, the target takes 1d10 more damage on a failed save, and the area of effect increases by 10 feet.
