Elemental Equilibrium on the fritz with minions.

Buddy of mine (who detests forums) is having a bit of an issue with his summoner, clearly related to Elemental Equilibrium.

Mobs are, for some reason, showing as resistant to fire damage on longer encounters. I've scoured the calcs on his build in POB and found no sources of fire damage coming from his character. It's not the Elder helmet's Immolate effect, as we've tested with a white helmet. He seems to think it's triggering from the specters (Solar Guard.)

Any ideas?

Is it possibly from the gloves ? On longer fights, do the enemies go into a burning state and then the added fire damage is applied kicking in EE resistance to fire?

Looked it up. According to internet, fire golem can cause Ignite which then is a burn.

Ahh, that'd do it. Thanks!
