Imagine a Minigun. Deals 180 potency per turn and increases Heat Gauge by 5 per tick, totalling 1800 potency and 50 Heat Gauge in 10 seconds, which is more than your basic combo can possibly do, but not enough to ignore your tools. I don't know how Flamethrower works but this would snapshot party buffs. The drawback is that you can't move for 10 seconds, making the job significantly harder. Would you want this for Machinist?
