Bagpipes of Berating

You can use an action to Blow the pipe's, which emits a thunderous blast in a 30-foot cone that is audible 600 feet away. Each creature in the cone must make a DC 15 Constitution saving throw. On a failed save, a creature takes 4d6 thunder damage and is deafened for 1 minute. On a successful save, a creature takes half as much damage and isn't deafened. Creatures and objects made of glass or crystal have disadvantage on the saving throw and take 8d6 thunder damage instead of 3d6.

Notes: Damage: Thunder, Deafened, Damage, Debuff, Combat
