Righteous fire : my bad math ?

Hi,

Well i dont get it : i have 91% fire resist, 7% regen life from passive skills and 3% from equipment, but still, i loose life and cant reach 1 life after some seconds.
I use low life stuff (Ambu's charge, Araku Tiki, rise of the phoenix...) combined to an aura with blood magic that keeps me under 35% life. Could plz someone explain me why it dosnt work ?

Do you have inner force?

Or any increased burning damage passives or gear?

Yes i do have inner force and some passive burning damage boost

Do you mean that the 100-91% resist = 9% unresisted damage is boosted by both inner force and burning damage boost ?
Indeed that would make a large difference...

Yes, righteous fire damage (against both you and enemies) is boosted by inner force and burning damage increases. If you want to use it with a bunch of burning damage increases stacked up, you'll probably need to spam ruby flasks.

Time to use few regrets. Thank you for these explainations !
