This is a somewhat silly GLOG class I made for an adventure I hope to publish (here) "soon", called "the Yamac Sauce Caper". This has not been play-tested as a PC. As a "helpful" NPC? 100% this works :D
So you thought being a cannoneer was special. Pfff. What if you are the cannon?
You are a cannon with all that entails. You somehow can talk, see and perceive as a human. You don't need to eat, but you can eat a load of gunpowder, somehow, to heal as if you had had a lunch.
You gain 1 hp and 1 AC per template (your AC at level 1 is like leather). If someone fumbles against you, they break their melee weapon against your hard metal barrel, or injure themselves for 1d3 dmg if using natural weapons.
A: 10 feet per round, aim yourself (you have +2 to hit), bombard's eye
B: 20 feet per round, Powder eater. fast fire
C: 30 feet per round. Ram, Safe
D: Self fire. Range
10 feet per round: You have gained the power to roll yourself around at fairly slow speed. You progressively move faster
Aim yourself: You can aim yourself, possibly achieving greater accuracy
Bombard's eye: As per Skerple's cannoneer power
Powder eater: Eat a load of powder to heal as per a ration (like taking lunch)
Fast fire: Your advice and assistance makes you easier to use. An untrained crew can fire you as fast as a trained crew, and a trained crew can shave off a round off their loading time (again, consult's Skerple's excellent rules).
Ram: You can roll into someone and ram them with your iron tube, inflicting 1d6 dmg
Safe: You are now completely safe to fire. If a roll indicates a serious misshap, the shot is instead interrupted (you know things are wrong)
Self fire: You cannot load yourself, but you *can* fire yourself
Range: Your range is increased by 50%
