Hellish Cannon

Today I came up with a concept for a very unusual hellcannon for the Alchemists of Chaos. Looking over the Hellcannon entry and the new 8th edition rules I realize what a great option it is. It's a very complicated item. I still don't understand how it works entirely. Can it move and shoot?

It was busy today as usual, for a Monday. After work I headed to the Spaghetti factory for dinner with the family. My kids are an absolute delight.

I am very tired, so no more for now. I'm about to pass out from exhaustion.
