I think you’re at the right level to try Hellborn. You should play around with points in the tier 1 skills, I have 3 in BBB and 2 in Fuel the Fire, and you may not want to invest heavily into Flame Flare. Elemental Elation, Delusional Damage, and Elemental Empathy are the skills I would say you can’t do without. DD will allow you to self ignite with other elements so it helps with mixed media (armor/flesh) maps, Fire Fiend lets your melee ignite you and enemies as well as doing some silly stuff to fire rate and accuracy. Legendary Torch is the move, but until you find one Toast coms are your friends (I like razed without Pain is Power). I believe health stacking is the best, so adaptive shields until you have a Rough Rider or Flame of the Firehawk. A good slag (you won’t really “need” slag until UVHM, but it’s not a bad habit to have) nade will do good works for you, betties and transfusions are good. If you have access to Tiny Tina nades a Magic Missile (or Fire Storm, or any AOE Vladof nade, if you are willing to slag with a gun). One last thing, when I started Hellborn initially I began to prioritize elemental effect chance over damage because it facilitates self ignition and gets you quicker access to Elemental Empathy heals. Now get out there and set Pandora on fire.
