Banshee Choker

While wearing this choker, once a day, as an action you may cast the Shatter spell without using somatic or material components. However the spell centers on you, though it does not affect you. Rather than a thunderclap, the spell sounds like a scream. Charisma is your spellcasting ability for this spell. You regain use of the spell at the next dawn.
