Eficacy support gem with RF

I understand that the damage overtime portion of the gem does nor work with RF because RF is not a dot.

However, efficacy also grants MORE spell damage. RF is a spell so that portion of the gem should work, I don't see why.


Also, how come witch fire brew works with RF and that is increased damage over time?

You have your modifiers mixed up. The damage done by righteous fire itself is affected by damage over time, and not spell damage. Efficacy only applies to any skill that has a hit, or has a duration, such as Essence drain, Blight, Scorching ray, and Searing bond. Righteous fire doesn't hit, or have a duration, so it can't use the gem.

Ok,

does the damage over time from the jewel below works with RF?






and also, why isn't RF affected by spell damage, it's tagged as a spell.

The following modifiers apply to Righteous fire equally: Damage over time, Fire damage, Burning damage, Elemental damage, and Area damage. General % damage boosts like the one that can be found on jewels also works obviously.

It's only a spell in the regard that its something that you "cast", but the effect that comes after that is not a spell. This is to prevent it from boosting its own damage with the % more spell damage modifier from the skill.

thanks for the clarification. :)
There are four Damage sources: Attack, Spell, Damage over Time, and secondary Damage. These four are all mutually exclusive, and unless explicitly stated otherwise, modifiers to one source will never apply to other source-types.

The DoT from RF is a Spell effect, but because it's Damage over Time, it is inherently not Spell Damage.

^What they said.

As for why Efficacy doesn't work, Efficacy (and Swift Afflication) requires the skill to either have a duration or 'hit' (so that it can potentially apply an ailment). As a damage over time skill, RF doesn't hit, and RF doesn't have a duration on its own, so Efficacy can't support it.
