Self-Ignition Information

Hey everyone. I was advised to post this on the new forum, as I currently have it only on the old one. I’ve been running some tests with Krieg (on Steam), and decided to do some testing with his self burn.

  • The base duration appears to be 5 seconds. This increases by one second for each point in Flame Flare.

  • The self burn damage is not determined by the DoT that procced the burn. Seems to be some static range which I haven’t determined. I…didn’t start the test at level 6, so I don’t know the base or how it scales. Sorry. I can tell you that it deals about 22000 damage at level 60, and about 24300 at level 61. It does behave like regular fire damage though, dealing reduced damage to shields and increased damage when shields are down.

  • Burn, Baby, Burn decreases the self burn damage you take. The damage reduction increases for each level in the skill, with diminishing returns. Shoddy data collection only ended up giving me ranges, so I’ll say that 1/5 seemed to deal roughly 12.5% less damage, while 5/5 seemed to deal roughly 32.5% less expected damage. It doesn’t seem to affect external sources of fire damage, and I while I couldn’t test external burn damage too well, a brief test of standing in the wreckage of a fire barrel didn’t seem to change the number either. If anyone has a better method of testing external burn damage, please let me know.

  • Burn damage from a common Torch mod increased the self burn damage by…some amount. The damage range barely changed between levels 60 and 61. Testing a fire Bone of the Ancients (29%) also increased self burn damage, but seemed to increase the average damage by roughly 20%. A Slayer of Terramorphous mod with 23% Burn Damage increased self burn, averaged to 17.5% increase (very weird, I don’t understand this formula anymore). A 24% Fire Relic produced numbers similar to the Terra mod. So yeah, if you up your fire and burn damage with relics and mods, you’ll hurt yourself more. Hooray.

The following is an excerpt from my original thread, describing testing method.:


The test was run on a computer with Krieg at level 60 and 61 in UVHM, no relic, mod, BAR, or shield. All data listed was tested at level 60 unless otherwise stated. I leveled Fuel the Fire, Pain is Power, and Delusional Damage, tested DoTs with both a level 52 Shock Rightsizing Plasma Caster and a level 59 Fire Rightsizing Bitch, with a level 54 Neutralizing Hornet used just once to confirm that the DoT that triggers the self burn doesn’t alter the damage received. Each test fell within a very tight range, so that was nice.

Next, I respecced and leveled only Fuel the Fire, to test some rather useless stuff. One random duration of self burn did 38637 damage at level 60, and 42382 at level 61; ignoring the damage multiplier for flesh, the numbers drop to 22078 and 24218. I then leveled Burn, Baby, Burn to 5/5, to see if increased burn damage increased the self-burn, and if it’d increase it by the base 35% or the on-fire boost to 110%. However, one random duration of self burn did 25315. I respecced again, leveled FtF, equipped a white Torch mod with 45% Burn Damage, and took 57232. Respecced again, grabbing only BBB; this was to test whether or not it was BBB specifically or the self-ignite chance decreasing the damage. The figure I got was extremely close to the number I listed above for my first test with the skill. Tested it multiple times with BBB at varying levels. The first test for each level, from 0/5 to 5/5, yielded these figures: 39383, 34392, 30460, 27928, 26869, and 25313. I also ran a test with a 45% Torch mod + 10/5 BBB, and took 27734.

I ran other tests with every Fire and Burn Damage boost I could find, and every one except BBB boosted the damage.

I didn’t see this info anywhere, so I figured I’d share just in case. The most interesting part is BBB’s damage reduction. This also presents an interesting case with Legendary Torch mods; for general gameplay, grabbing the weakest Leg Torch mod and throwing a point or two into BBB would yield the most survivability, especially if you’re running a Flame of the Firehawk.


Sorry to necro this thread, but it seems the best place to post additional information.

Self-burn base damage is 3% of Krieg’s base health (that is, health before gear and skill buffs) per second. Self-burn damage follows standard fire elemental affinity, that is, 40% versus shields and 175% versus unshielded flesh, so it’ll look more like 1% per second against shields, and 5.25% per second once the shields fall.

Self-burn damage is increased by Fire Elemental relics, Bone of the Ancients, and Torch and Legendary classmods. The increase is scalar: a +56% Legendary Torch classmod will multiply Krieg’s self-damage by 1.56.

Self-burn damage is decreased by ranks in Burn, Baby, Burn. Additional ranks provide diminishing returns: 1 rank gives you 88% damage, 5 ranks gives 64% damage, 10 ranks gives 45% damage. This decrease appears to be separate from damage resistance (see next item). Ranks in Fuel the Fire have no effect other than enabling additional probability of self-burn.

Self-burn damage is also decreased by general damage resistance, include the Rough Rider shield, ranks in Numbed Nerves, and ranks in Taste of Blood if Krieg is rampaging. It is not decreased by Resistance relics or a Skin of the Ancients. (Note that those two DR skills underadvertise in their tooltips the actual damage resistance that they provide: in the traditional notation, such as used by I’m the Juggernaut and the Rough Rider shield, five ranks in Numbed Nerves provides +100% damage resistance, as do five ranks of Taste of Blood with Bloodlust stacks maxed.)
