Engineer Burn Burst
Flame Turret would probably be a better choice for burning than Rocket Boots, since Throw Napalm is much easier to land and you can throw down the turret afterwards for more burning. It’ll definitely be a build worth trying in the pvp lobby at the very least.
I am not trying to force max burning here. I just wanted to list some of the skills.
Propably just going flamethrower + bombkit will allow for decent burst burning. Lay your bombs, proc your incendiary powder trait and ocasionally add those 6 incendiary ammo stack to the fun.
May I suggest Flamethrower 4# firefield infront of you followed by Mortar 1 spam with quickness. Also get that Burning durration up.
Dont forget air blasting right after stacking lots of burning!
Worst case scenario only the last condition is extended, best case is theyre all extended!
