would like to try a fissure pvm druid but i dont know if there is a way to break the fire immune with raven lore, facets and infinity merc?

The only things that can break immunes is: conv aura and lower resist curse.
All sources of -res only comes into consideration when immunity is broken or mob wasnt even imune.

I don't know if it will be effective. But maybe holy freeze act 2 Merc?

Molten boulder and volcano work well.
