Chance to Self Ignite Formula (+ 'video proof' at 100%)

BBB = burn baby burn
FtF = fuel the fire

Both those skills increase the chance that Krieg self inflames when/after setting an enemy on fire by whatever means ( krieg takes damage while on fire and can even die from it, but his Hellborn skill tree skills tend to provide extra bonuses while Krieg is on fire so it can be a worthwhile tradeoff )

Chance to self ignite after igniting enemies =
0.07 * BBB Rank (+ BBB skill from COMs works) + 0.07 * FtF Rank (+ FtF skill from COMs DOES NOT APPLY - BUG - UI LIES)

Fuel the Fire is bugged. Extra +Fuel the Fire skill from COMs DOES NOT increase krieg’s chance to self inflame despite the UI (falsely) claiming otherwise

So it can reach 100 % chance to self inflame with 10/5 BBB (+5 BBB from COM) and 5/5 FtF . ( 0.07 * 10 + 0.07 * 5 = 1.05)
// Roll to set target on fire
# Chance to trigger effect 1.0000 * 30.0000 * 1.0000 * 1.1377 * 0.6000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 = 0.2048  
// SELF INGNITION CHECK ( 0.07 * 10 + 0.07 * 5 = 1.05)
# Dice Roll: 0.76561 vs 1.05000  
# Damage Type =          FIRE ; ElementalMul = 1.00000; ( GrenadeMul = 1.14080 ); address =   3E973818 
# vsShieldMul 0.40; Intermediary Damage Value 0.50000000  
// IF chance to self ignite succeeds - A roll to apply fire DOT on self is faked/forced ( F4 = 1k)
# Chance to trigger effect 1.0000 * 15.0000 * 1.0000 * 1000.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 = 150.0000  

I only tested legendary torch so far. I will take a look at other COMs that boost fuel the fire to see if they work …

EDIT:

BUG CONFIRMED (twitchy reaper COM +5 FtF test):
# Chance to trigger effect 1.0000 * 30.0000 * 1.0000 * 1.1377 * 0.6000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 = 0.2048  
# Dice Roll: 0.01943 vs 0.70000 ( 5/5 + 10/5) ( 0.07 * 5 + 0.07 *5 = 0.7)
# Damage Type =          FIRE ; ElementalMul = 1.00000; ( GrenadeMul = 1.14080 ); address =   3E973818 
# vsShieldMul 0.40; Intermediary Damage Value 0.50000000  
# Chance to trigger effect 1.0000 * 15.0000 * 1.0000 * 1000.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 * 1.0000 = 150.0000  

For Fuel the fire skill only the chance to self ignite doesn’t benefit from the COMs , the extra chance apply elemental effects on kills works. Notice F9 =5 in the combat log output bellow. (100 % + 400 % = 500% ) at 10/5 fuel the fire fuel the fire provides 400% extra chance to apply elemental effects for a short while after a kill…

# Chance to trigger effect 1.0000 * 30.0000 * 1.0000 * 1.1377 * 0.6000 * 0.9000 * 1.0000 * 1.0000 * 5.0000 * 1.0000 = 0.9215

My god sorry for waisting ur time should have actually thought about it thank you tho

bump … added video link

I myself did a fair amount of testing with self ignites. Over all a very cool idea with a lot of programming issues, mechanical flaws, and bugs. I it is good to know that COM bonuses to Fuel the fire are bugged. It diminishes the value of the Legendary Psycho COM. Over all Self Ignite has a ton of issues especially when playing with others. One of the worst is when playing with Krieg’s Soul Mate Maya. Having Ruin, Helios and Converge can make self igniting frustrating at times. Luckily Chain Lighting comes in with the save when you have it on farm. Low durations DoT very high chance to apply shock and it will hit multiple things in a wide range. Only problem is you need to not only have access to this grenade mod but be half way down the Hellborn tree.
I believe I made a topic some time ago about self ignite mechanics but this was also before the new DLC. It’s possible things have changed.
