This weapon is well known more-so from its original wielder, than for its abilities. A self-conscious introvert was sick and tired of people running their mouths and talking non-stop. With his creation of this weapon, he was known to say, "No more warning cries, no more endless monologues, and best of all, no more spells with verbal components."
