Idea:Cannon Hammer

The Cannon Hammer is a Blademaster weapon that is able to turn from a hammer into a cannon

Explanation
The Cannon Hammer was created from years of experimenting and modifying the Gunhammer into the perfect hybrid of hammer and cannon, because they are so new very few smithys actually know how to forge them which makes them extremely rare and highly prized by hunters.
