I decided to take on a Bloodlust/Hellborn build, which never caught my attention since Mania it is a must on every K in my opinion (RtB, StV, StF, etc.). But I took the step and decided to make a run using that skills. Gun focused playstyle. A DP run is on the sights and maybe turn this K into my co-op char if it is viable at OP8.
Came with this build, throwing some points randomly since I’m not pretty fond of my Bloodlust tree knowledge (excepting Bloodplosion, and BxB).
I tried this once, but wasn’t very successful, mainly because I’m not a Hellborn player. But I would go with this spec instead. Since you don’t have RtB, you’ll need a good Moxxi weapon to keep yourself healthy (Rubi, Grog, Hail, etc.). If you’re careful with your health, you can toss the Grog, but it does come in handy.
If you don’t have a zero fuse time grenade, move the points from blood twitch to blood overdrive instead. I would also think about using a Blood instead of a regular stockpile relic.
If you’re going with a bloodlust-hellborn then forget anything related to BxR’ing so change those points from Taste of Blood and Buzzaxe Bombardier into Blood-Twitch and Feed the Meat. I would probably go with [something like this instead][1]
Another thing I would suggest would be trying out a quasar first for clustering, secondly for self-ignition through Delusional Damage. or maybe a slag betty for AoE slagging and less weapon-swapping.
Finally, like Gulfulf said you should try a Blood of the Ancients instead of a Stockpile, Elemental Empathy gives more than enough healing even without Burn-Baby-Burn so you’ll be able to get back quickly to full-health.
