Life Degeneration Effect: While this skill is active, the player and surrounding enemies will take fire degeneration damage (damage over time). This damage can be mitigated with fire resistance for both the player and surrounding enemies. Righteous Fire will damage energy shield and keep it from recharging while the skill is active, but it can still regenerate if the player has life regeneration and the Zealot's Oath keystone or any other sources of energy shield regeneration.

Spell block and spell dodge: Keystones, passives, and item mods meant to avoid or block spell damage will not work on Righteous Fire's degeneration damage. Elemental Reflect only reacts on hits. Because of this, the RF degeneration does not trigger reflect.

Chaos Inoculation: Characters with only 1 life due to Chaos Inoculation cannot inflict damage with Righteous Fire's degeneration because Righteous Fire will stop instantly upon activation.

Mind Over Matter: Mind Over Matter does interact with Righteous Fire degeneration and will drain mana.

Stopping Righteous Fire: Righteous Fire will continue to drain the player's HP until there is only 1 HP left, at which point it will turn off. The effect can be ended prematurely by any effect which removes burning, such as flasks with the "dousing" suffix. Taking the gem out of its socket will remove the skill effect, but will not stop the degen effect.

More Spell Damage Affix: Righteous Fire provides a large bonus to spell damage during its effect. Note that this is more damage stat, meaning it is a multiplier to overall damage.

Damage stats: The following stats apply to the damage Righteous Fire deals to enemies: Fire damage, burning damage, damage over time, area damage and generic "increased damage" or "more damage". These stats do not apply to the self-inflicted damage from Righteous Fire.

Increased and decreased spell damage does not affect the degeneration damage because spell damage and damage over time are two distinct and mutually exclusive damage sources. Aura modifiers don't affect Righteous Fire because it's not an aura.
