Thunder Bomb

You release a wave of noise and vibration to knock foes off their feet. All creatures within 30ft of you that don't have half cover or better against you must make a Constitution saving throw. On a failed save, a creature takes 4d8 thunder damage and is knocked prone and is deafened until the end of their next turn. On a successful save, a creature takes half as much damage and isn’t knocked prone. The explosion will knock over or scatter any medium or smaller objects that are unattended or unsecured in its path.
