So I have a classic meteorb sorc, pretty strong, and I want to use frozen orb as my main attack.
I already have a nightmare defensive act 2 merc with me for defensive aura and I was going to use fortitude and infinity with him, but now I'm thinking it might not be the best route.
What is the better combo? A different type of act 2 merc and giving him doom, which does more damage, gives him holy freeze aura, and lowers enemy cold resistance by 45%, or act 2 nm defensive which has holy freeze aura and then I give him infinity, which gives him conviction aura, and does not quite as much damage. I'm not sure which would lower resistances more for enemies in hell, the conviction aura or the -45% of doom. I don't know what the other act 2 merc auras are either, as holy freeze aura is a must for me I think.
There are also a variety of other things like prevent monster heal, crushing blow, deadly strike etc. that each of the things have that can influence my decision. I basically want my merc to be able to tank and kill all cold/fire immunes for me, and possibly remove cold immunity from some monsters in hell.
I'm sure others have broken this down before and understand the immunities of the different scenarios so if someone could let me know i'd appreciate it.
Help please and thank you.
