Bangarang

You conjure a series of disruptive and annoying sounds that plague the air of the immediate area. As an action, you create an area of noise in a 120-foot sphere centered on you. Any creature that is inside of or enters the sphere must make a Constitution saving throw or suffer (4d6) thunder damage and is stunned. A creature affected by this spell can choose to repeat the save at the start of its turn. On a successful save, the creature takes half as much damage and is not stunned.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
