General thread about righteous fire, please check first as it contains information from this guide but easier and quicker to view
http://www.pathofexile.com/forum/view-thread/832331

If you're new to the righteous fire skill please take a look into the "Intro to righteous fire and damage mitigation" section to know how it works. It is a tricky skill that needs preparation before you can use it and very math based. But no problem you won't need a calculator thanks to our friend Maxwel you can use the above spreadsheet to see how much damage righteous fire does to you, how much resistances and life regeneration you have and how much damage it does to enemies. Just make sure to fill in all the green cells with the right numbers!

RF damage taken


RF damage to enemies

Pros
- Very cheap
- Very good DPS
- Tanky. 6k+ hp, 90% physical damage reduction with 7 endurance charges and without granite, 100% fire resistance with ruby flask and 90% lightning resistance with purity of lightning and topaz flask
- Easy to gear and overcap resistances
- Reflect and corrupted blood inmune
- Only 4l needed

Cons
- Cannot do -max resistances, half/no regen and blood magic map mods
- Vulnerability map mod can be done but late game or with specialized gear (blooddance boots)
- Rise of the phoenix unique shield needed
- Alternate skill to kill totems is needed as RF doesn't damage totems
- Fun really starts at level 65

Before we go into quite an extensive guide I want to show how I built up my second RF character, the one I'm currently playing in nemesis (level 88).

Right after my first RF character ripped to a very angry torture chamber boss I decided to rebuild it with literally no currency. No problem, all you need is a nice 2h weapon to start leveling, the rest will follow. After roughly 20 hours played and level 68 I was setup to start RFing again, here is a link to the post I made on this thread: http://www.pathofexile.com/forum/view-thread/666667/page/7#p6014564

Total costs: ~40 chaos

Which could probably get down to ~30 chaos as we use dual redbeack's instead of searing touch now.

However from all the gear you only require one piece for this build, rise of the phoenix unique shield.

Why is this build so effective? A couple of reasons:

- Life boosts survivability and damage
- Finding the right gear is both, easy and cheap
- Clearing speed is very fast, which makes getting currency from farming to progress quite easy

So, interested and curious in how this all fits together? Then read further!

RF

The spell is a buff and a debuff. Once it's cast the character will be burning taking 90% life and 70% energy shield burning damage per second until life reaches 1hp, a flask with "dispels burning" mod is used or an area change. While the character is burning it will damage enemies for 50% of the maximum hp and 50% of the maximum energy shield in a small area around the character and it will make your spells do 40%-59% more damage. The damage is damage overtime similar to fire trap's burning damage (not the explosion)

RF is an imprint of cast moment (snapshoot). This means any mods from gear that is equipped at the cast moment will apply to RF until RF is dispelled. You can remove or change gear after RF is cast and the skill, together with any mods will still be on. An exception is life and ES, this will update as soon as the gear is changed.

Increasing RF damage to enemies
Below are the possibilities to increase the damage that RF does to enemies
- Increasing character's life and energy shield
- Debuffing enemies: vulnerability curse and lowering enemies fire resistance with flammability, elemental weakness or elemental equilibrium (damage done by RF doesn't trigger elemental equilibrium)
- Increased burning damage
- Increased fire damage
- Increased elemental damage
- Increased area damage
- Increased DOT damage
- Increased damage mods from items if they're equipped at the time RF is cast

Increased RF damage taken by you
The following will increase the damage taken from RF
- Increased effect of buffs on you. For example the Inner force passive cluster
- Vulnerability curse. This will increase DOT damage taken by 40%. Can be dispelled by flask
- Flammability and elemental weakness curses. Can be dispelled by flask and/or overcapped

RF damage taken mitigation
The damage taken from RF can be mitigated by increasing maximum fires resist and regenerating life. If the mix between resists/regen is higher than the damage taken from RF you will take NO damage, if it's lower you WILL take damage

Examples
RF does 90% of you maximum life as fire damage, you have 85% fire resist and 10% life regeneration, the damage taken from RF then would be: 90% * 0.15 (we mitigate 85% due to fire resistance) = 13,5%
We would take 13,5% of maximum life as fire damage, we regenerate 10% life the total damage taken would be: 13,5 - 10% = 3,5% of maximum life taken as fire damage

Now the same but we have 90% fire resistance. Damage taken = 90% * 0,1 = 9% and we regenerate 10%. Total damage taken = 9% - 10% = -1% This means we regenerate 1% of life, we outregen the damage taken from RF and regenerate an additional 1%

After this intro on how RF works now we go to how it can be sustained without taking damage.

Going RF
The earliest you can switch to a sustainable RF will be at level 65, this is when you can use rise of the phoenix unique shield. This unique is a must for this build.

Ideally you want to take no damage from RF. There are two ways to mitigate the damage taken from RF, fire resist and life regeneration.

This base is a guideline about how to calculate a sustainable RF. There are other options, endurance charges with life regen per charge passive, blooddance boots with frenzy charges, not taking the inner force cluster, etc...work out what you like the most :)

Below is a base build at level 65 that will let you sustain RF with the right level gems and some explanation.

Needless to say don't forget to start leveling vitality and purity of fire as soon as possible :)

At level 20 purity of fire gives +4 to maximum fire resistance. At level 23 and above purity of fire gives +5 to maximum fire resistance, this is the cap for the aura.
