skill rank of StV does not affect the self damage
skill rank of FtB does however
damage done to flesh vs shields is same
also I thought the formula was 1/(1+total damage resistance)
it seems that ALL grenade damage affects self damage
I tested this by having my BAR on
and trying to self hit me
I did 15.6% more self damage
which is exactly same as the amount of Grenade damage I have with BAR
perhaps self damage is counted as grenade damage?
Indeed it is… I probably should stop trying to multi-task.
I suppose it could be grenade damage but not necessarily explosive damage (hence the no difference when applied against flesh or shields) but I could be wrong, I tend to do that a lot.
Would also explain why when fuel the blood is active, his thrown buzzaxe with the Buzzaxe Bombardier skill specced in to does insane amounts of damage both to the enemy, and to himself when he hits himself.
Oh, this is smart ! The Dynamite attachement may count in the self-damage calculation 
! Can someone test StV with and without Buzz Axe Bombardier (with FtB triggered) ? I think we’ve found why StV does so much damage when FtB is triggered.
Instead of proccing FtB you could just turn your BAR on
Its much less trouble that way
And without FtB BXB doesnt make a difference in self damage
From what I remember the thrown axe with BXB does count as grenade damage
I didn’t say that, I said : try to proc StV while FtB is active, but without BXB. It should do less self-damage without BXB.
Yeah ik
Just said that as a minor note
Also
The FtB test I did was without BXB specced
So all there needs to be done is BXB specced, grenade damage bonus included StV test
Im not on my pc rn so cant do it yet
So BXB and FtB are the reasons why StV does so much damage, even with the Rough Rider.
(hypothesis, testing it in a few minutes)
The FtB tests I did show that theyre doing a ton of damage without BXB
If BXB increases that
Ouch
But since speccing into BXB itself doesnt increase the self hit damage
Im doubt FtB would have a bigger effect with FtB specced
Ofc as was the case with Rough Rider I could be wrong
just did a quick test
and nope BXB does not affect the self hit damage
Just did the testing, BXB doesn’t affect it at all, you are right.
But FtB does increase self-damage from StV, why the hell ? I don’t know ._.
Grenade damage affects self hit damage
So maybe self hit is classified as grenade damage in the game
Also in case you didnt know
I did make a separate thread of the testings on self damage
Gearbox, WHY ???
Oh I know it does, i’ve known it for a long time. It also boosts the thrown buzzaxe melee damage through the roof so the optimal way to do that now is Kill something with regular melee, then throw axes until it runs out. Rinse and repeat. WHY they chose to have it like that, no idea. Could be a code error.
No Idea
Maybe only a few damage types can cause self damage
So they used grenade damage out of those
could have been. probably didn’t think that through to well lol
