Bass Clarinet 

An instrument descended from heaven. Forged by God himself in the fires of Mt. Buffet with wood taken from the trees of the Garden of Eden, it is said that when one such instrument is played, storms dissipate and seas are calmed. In the hands of an expert, the Bass Clarinet's power can be weaponized, calling in lightning to crash down upon his enemies.

A holy weapon of mass destruction. We call it- the bass clarinet.
