Dubstep Blast

You hold up the stuffed mynah bird, and shout to the rhythm of Ghost Ship by Teminite. A massive blast of pure sound comes from the beak of the bird, hitting everything in a 100 ft. cone. Creatures hit by the awesome music must succeed on a Wisdom Saving throw or be charmed by you and take 8d12 thunder damage, taking half as much damage and evading the charm on a successful save. This spell deals double damage to buildings and structures.
