With this setup your burns will tick for 634 each and bleeds for 104 each.
One of the most important facets of this build is the Rocket Kick(8 second burn) and Incendiary ammo(up to 13 second burn). These both apply burns. That and Rocket Boots is our get out of dodge break stun skill, don’t hesitate to use it.
Flamethrower is in this build for the kit refinement trait, switch to this weapon with an enemy near you and you apply a 3 second burn(the traits make it 3 seconds, that’s 1.8k just for swapping weapons) to nearby foes, you can then use the aoe blind and pushback from it and just switch back to whatever else you need.
Close up Blow Torch burns will last for 9 seconds, couple that with sustained poison and bleeds you can be doing up to 1.4k dps, not to mention confuse bomb hits for nearly 800 a tick.
