How to improve Righteous Fire damage as an aurabot?

Hi, I play as an aurabot (Necromancer) that runs 12 auras with 2 of my friends. A CoC Cyclone Discharger and RF guardian.

While I effectively 6x the discharger tooltip damage, I don't seem to bring much to the table in terms of damage for my friend's RF.

On top of that, my friend's RF runs Elemental Equilibrium which means my Anger aura doesn't complement well with it at all since he couldn't reliable proc EE with another elemental damage since any spell will have fire damage too.

What could I do to benefit this party more?

Assuming he plays as Pure RF, there isn't much you can do.

Purity of Fire, Vitality help but RF is a weird skill that way. It doesn't even benefit from a 5/6L as there are really only 3 gems that support it well:
Elemental Focus
Increased Burning Damage
Increased AoE/Conc effect.

You should probably replace Anger with Envy in that party if you can. He'll proc his EE fine and the discharger wont lose much, if anything.

~Myth

Pure degen builds are very hard to scale. You're already giving him a lot of %increased damage through Commander of Darkness, and maybe you could proc EE for him on bosses, if you have Anger on Generosity. Other than that, you can cast Scorching Ray on bosses to reduce fire resistances further, and use multiple resistance reducing curses.
