Cartridge Cannon

A Cartridge Cannon is a powerful Gem Cartridge weapon that can be fired without a medium such as an arrow or catapult ball.

Description
About the length of a man's forearm, it is too powerful for anything less than professional military use. The recoil is powerful enough to dislocate shoulders, and, in extreme cases, rip off arms. The length of the muzzle determines accuracy, longer it is, the more accurate the beam is.

The shape of the muzzle is sometimes up to the user, if he has access to the gunsmith who made it. Seeing a square, round or even triangle shaped muzzles are not uncommon (if you happen to even see one). One design allows the beam to be expanded after leaving the opening and it easily becomes more massive than the wielder. A few designs are made by the competing Taisen Industries and Kill Industries Limited Licenses.
