Excalibur

The most powerful weapon in the history of Shibusen, any meister can make use of Excalibur to overcome nearly any enemy--if he can put up with the strange little man's personal quirks. Pretentious, self-centered, and capable of talking the ear off a brick wall, Excalibur endlessly lectures his charge on his many exploits and makes insane demands of anyone within earshot. It's little wonder why he spends most of his time exiled to a remote cave.
