One of my players just built himself a Double Hackbut
The rules on it are not so much vague as non-existent though.
You need a full round action to set it up - that's clear.
You can "wheel it around", but does that mean just turning it to face other directions or full freedom of movement?
Assuming you can move with it then can you move at full speed? How about double-move and run? Can you 5' step? Can you lift it up a step or do you need to set it up again afterwards? What about a full flight of stairs? What effect does difficult terrain have?
Does anyone have any decent information on RAW or RAI as to how on insert fantasy land of choice this thing is supposed to work?
Right now it seems obscene, clearly better than all other firearms. It's also supposed to have some sort of movement limitations to bring it into line - but they are so vague it's impossible to see what they actually are!
