Bossa’s Bossa Nova

A forceful sound penetrates the mind and body of the enemy target. The target must make a Constitution saving throw. On a failure the target takes 3d6 force damage and has disadvantage on the next attack roll or saving throw. On a success the target takes half as much damage and has no disadvantage. When this spell is used at a fourth level or higher damage increases by 1d6 for fourth level or higher.
