GünterbussThis weapon is named Günter. He has Intelligence 10, Wisdom 11, and Charisma 9. He can speak, read, and understand common (but he can't speak on a turn he's used to attack, because his mouth is firing shot, of course). Hearing and normal vision out to 120 feet. Neutral alignment and seeks his creator.
Günter can chew up pretty much anything for use as ammunition, but he prefers wine casks and coal.
