Righteous fire resource guide

Hardcore

Softcore

The skill is a buff (it damages enemies) and a debuff (it damages you), it is not a spell. 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 character's maximum life 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. Once an enemy enters the area of righteous fire it will start taking damage

RF is an imprint of cast moment (snapshoot). This means any applicable to RF damage 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.
Note An exception is life and ES, this will update as soon as the gear is changed. I tested this long ago, if someone can verify it still works like this please let me know.

Righteous fire does the following fire damage:
- 90% of character's maximum life
- 70% of character's maximum energy shield

Damage taken formula


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%.

The damage taken from RF can be mitigated by increasing maximum fires resistance 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%

Below are the possibilities to increase the damage that RF does to enemies
- 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)
- Burning damage
- Fire damage
- Elemental damage
- Area damage (this includes concentrated effect)
- DOT damage
- Damage mods from items if they're equipped at the time RF is cast. For instace Readbeck's "100% increased damage while on low life" mod if you cast RF on low life

Damage done formula

The following works with regards to magic find and RF. Tests were done with IIQ as it can be verified easily. I assume IIR behaves the same way but I haven't tested it
- Snapshoot IIQ gem
- IIQ from gear on the character at the moment of killing an enemy. This means gear IIQ cannot be snapshooted

The following will not work with RF
- Spell damage
- Fire penetration
- Removing MF gear after snapshooting RF

There are a few ways to get extra maximum fire resistance
- Purity of fire aura. It caps at level 23 for a +5% to maximum fire resistance
- Uniques with +x% to maximum fire resistance like rise of the phoenix
- As of v1.1.0 the following passives give extra maximum fire resistance:
Diamond skin in the marauder area. +1% to maximum fire resistance
Fire resistance in the marauder area. +1% to maximum fire resistance
Elemental adaptation between templar and and witch area. +2% to maximum fire resistance
- 1% to maximum resistances from a corrupted chest armour

Total achievable maximum fire resistance

The following support gems work with RF:
- Increased burning damage
- Concentrated effect
- Increased area of effect
- IIQ
- IIR
- Empower (not useful)
- Enhance (not useful)
- Enlighten (not useful)
