A sudden loud ringing noise, painfully intense, erupts from a point of your choice within range. Each creature in a 10-­--foot-­--radius sphere centered on that point must make a Constitution saving throw. A creature takes 3d8 thunder damage on a failed save, or half as much damage on a successful one. A creature made of inorganic material such as stone,crystal, or metal has disadvantage on this saving throw. A nonmagical object that isn't being worn or carried also takes the damage if it's in the spell's area.
