To put to simply, look for the weakest enemy in a general mob, the one with the lowest health, slag it and throw a fastball at it, then slag everything around it and watch the carnage commence. You may need to kite a little to get everything close, lure running melee enemies back to the shooters behind cover then secure the kill, if you hit that critical health zone go into RtB and go ham, chances are that will be enough to set up a chain, just remember to always focus on the weakest enemy. Most other characters want to priorities the strongest enemies, badasses, constructors etc. but not Krieg, he works the exact opposite. If you land a melee kill while in BXR/RtB remember to throw those axes, Fuel the Blood and Buzz Axe Bombardier are your saving grace here!
It just comes with practice, and unlike what many may suggest Krieg is NOT useless in UVHM or at OP8, just get yourself geared and practice setting up chains, once you get that down it will be second nature
As always high Bloodlust stacks are the real key. Each stack is worth an extra 5% damage (I think it’s multiplicative) so big stacks = big death!
Remember it’s also based on Overkill damage (damage over and above what was needed to finish them off) so melee/grenade kill on the weakest enemy for maximum radius/chance to kill undamaged nearby enemies!
Don’t forget slag if you have the ability to get some out there before you kill (low level bouncing betty slag grenades shine here!) as this triples the damage but that’s getting into unfair territory!
Finally it’s better to not have the enemies all clustered together but spread out in a line where possible so that the explosion slowly works in one direction as this will allow for the biggest bonuses!
Bloodsplosion is based on Overkill damage, so be sure to debuff the weakest enemy and hit him as hard as you can to generate the highest Overkill damage as you can, and then just watch the explosions of life sweep the battlefield as you walk across it. Of course, slag is much appreciated for keeping the Bloodsplosion in “chainkill-mode”. Keep in mind you need to kill the nearest enemies AND generate more Overkill damage to make the Bloosplosion chain, as long as there are things to kill. You need the enemies close enough, but not too close, since the Bloodplosion will just take all of them out, instead of taking them down one-by-one to generate even more Overkill damage per Bloodsplosion.
If used well, this skill is absolutely insane. For example, here is some footage of me destroying Pyro Pete with White Gear only :
As you can see, the Overkill damage is the key here. As long as you can escalate your Overkill damage through multiple Bloodsplosions, you can decimate anything in the game. I’ve Bloodsploded Pete, Vorac, Terry, Dragons, Saturn and BNK3R (Saturn and BNK3R with a Diesel Blister COM + Corrosive Fastball.)
If you have questions, feel free. Hope this was helpful
My god Bloodsplosion is awesome. I’ve been messing around in Frostburn Canyon testing it out against bandits/spiderants. Highlight was killing Scorch in one hit by killing a Spiderling Slagga + Fastball = everything dies
It’s making me question whether RtB is required anymore though…
