Apeiron's Proof that sustaining RF on Life with pure regen works again viable.

have you tried blood dance unique? it adds 7% life regen and 14 cast speed just like that.

Yeah I am using them at the moment, when the build is finished I will only have +5 Frenzy charges though.

On a completely unrelated note:

Why is the templar left handed?!

Disgusting xD

I wonder at what level Purity of Fire scales up to 5% then. It seems logical that it would be possible if the 4% threshold is this low!

So basically it is not sustainable without relying on unique items?

You cannot make this sustainable righteous fire build based purely on passive allocation, skill/support gem useage and rare items?

also why does the path of exile wiki
http://pathofexile.gamepedia.com/Purity_of_Fire
show purity of fire to give 4% maximum resist at level 20? is this incorrect? I hear people saying you need 21...

am i right at presuming that at 81% fire resist (if the path of exile wiki is actually correct: 75, purity 4, passive 2) you would need;
17.1% of max life regen per second? (@1000 life * 0.9 dmg * 0.19 less fire dmg taken = 171 dmg per second in fire)

This unreachable with rare items, passive spending and gems?

Wrong. Purity of Fire is indeed 4% at level 20. It goes to 5% at level 23 and 6% at level 26. This is further boosted by Aura effectiveness nodes. For example, having 50% increased aura effectiveness makes a level 20 Purity of Fire provide 6% max resistance. The same way, a level 26 Purity of Fire would provide 9% max fire resistance. Goes a long way to help you sustain RF. Of course, unique items increase your max resist even more. Maybe there's a way to sustain RF without uniques, but I haven't tried to do so, since I have the uniques at hand!

I'm working on a low life righteous fire build using ES instead of life as defense.

If I calculated it right it should be possible. Using the same calculations as I did with my life based RF so it should be possible. I only need to farm up about 15 more regret orbs to give it a try. I am thinking about using the new Storm Caller skill with it, and possibly discharge or maybe freezing pulse... I still haven't tested a sporker yet though so I might try using one totem as well.

Thx Hrishi ive started leveling for it, and i saw the phoenix shield is actually quite cheap, i might use rejuvenation totem and a build similar to the OP's one and get all the improve aura talents possible on the board and slowly improve my build over time (possibly remake more characters) to use less and less regen and move towards more dmg as i get gear, quality gems and experience with the build/passive choices.

As i would like to one day be able to use the aura and have a frost witch build, using vitality clarity and purity of fire auras and quite a few curses. But i will have to work out what i can and cant sacrifice to get there. I prefer the Health build as i would like to have a small chance of doing chaos things rather than basically none if you go an ES build.
