Righteous Fire is a spell that applies a buff to the player, granting more spell damage, but also applying a potent burning effect that scales with the user's maximum life and energy shield to both the user and nearby enemies.

Mechanics

Skill functions and interactions (from wiki)

Damage over time effect: While the Righteous Fire buff is active, the player and surrounding enemies will take fire damage over time.

• The self-damage can be mitigated like regular fire damage over time: it can be shifted (e.g. ), resisted, reduced by elemental damage reduction (e.g. endurance charges, Eternal Damnation), or modified as damage taken (e.g. Soul of Arakaali).
• Damage can be taken by resources like energy shield, life, or mana (e.g. with ), and can be sustained with enough recovery for these resources, such as regeneration.
• Damage over time does not hit, and accordingly Righteous Fire's self-damage cannot be blocked, suppressed, or reflected. It also cannot be recouped or contribute to Cast when Damage Taken.
• The self-damage does not count as being ignited.

Stopping Righteous Fire: Righteous Fire's buff and burning effect will apply until the player reaches 1 life, at which point the buff is removed. The effect can be ended prematurely by any effect which removes burning, such as flasks with a Removes Burning on use affix. Unsocketing the gem out of its socket will remove the skill effect, but will not stop the burning effect. *: Righteous Fire cannot be activated if Chaos Inoculation is allocated, as the buff is removed immediately when the player is on 1 life (which is all the time with Chaos Inoculation).

More Spell Damage buff: Righteous Fire provides a large "more damage" modifier to spell damage during its effect, which is multiplicative with other damage multipliers. This buff does not affect Righteous Fire itself, as it does not scale with spell damage.

Damage modifiers:

• Modifiers to the following stats apply to the damage Righteous Fire deals to enemies: damage, fire damage, elemental damage, area damage, damage over time, burning damage and (fire) damage over time multiplier. These modifiers on the player do not scale the self-inflicted damage from Righteous Fire, though effects that cause the player to "take increased damage" do (e.g. or ).
• Spell damage modifiers do not scale Righteous Fire's damage despite being a spell gem as spell damage and damage over time are two distinct and mutually exclusive damage sources.
• Aura effect modifiers do not affect Righteous Fire as it is not an aura.

Duration scaling: Linking Righteous Fire with the support gems Lifetap Support or Arcane Surge Support causes Righteous Fire to gain a duration effect, allowing the skill to be supported by Swift Affliction Support and Less Duration Support, which normally would not support it.

Spell Totem Support: When linked with the support gem Spell Totem Support, the burning damage effect is cast and applied by the totem instead, based on its own maximum life and energy shield, not the player's. Righteous Fire's more spell damage buff does nothing in this case.

Inspiration Support: If Righteous Fire is linked with Inspiration Support, as long as the player can gain s from another source (such as a movement skill linked to another Inspiration Support), then Righteous Fire will benefit from the Elemental damage scaling from Inspiration Support.

Lifetap Support: Similarly, if Righteous Fire is linked with Lifetap Support, as long as the player can gain from another source (such as a movement skill linked to another Lifetap Support), then Righteous Fire will benefit from the damage scaling from Lifetap Support.

Ancestral Bond: It is possible to use Righteous Fire with the keystone, though the skill will only burn the user, not nearby enemies.

Gluttony of Elements: If is used with Righteous Fire, the skill will restore life over time instead.

Damage stacking: Multiple sources of Righteous Fire (such as from multiple players) do not stack. Instead, the source with the highest damage will take effect on the enemy.

Sustaining Righteous Fire

The most straight-forward way of sustaining Righteous Fire's burning damage is combining Fire Resistance with Regeneration. Depending on the player's resistance, less regeneration is needed to break even. The base formula is:

: burnDegen = (lifeburnLife + ESBurnES) * (1 - fireRes) * (1 + dmgTaken)

where life, ES and fireRes is the characters maximum life, maximum energy shield and fire resistance. burnLife and burnES is the percent of life and energy shield that Righteous fire burns for and dmgTaken is the sum of all Damage taken stats, such as 10% reduced Damage taken from Damage Over Time from the Soul of Arakaali Pantheon power or #% increased Damage taken from .

The maximum Fire Resistance can be increased by allocating passive skills such as , using the Purity of Fire aura and utilizing modifiers on various rare or unique items such as Rise of the Phoenix, up to a cap of 90% maximum Fire Resistance.
