My clay golem is only good against bosses. Fire golem has twice the hp of clay but his aura annoys everyone and they always focus him down real quick. So I decided I will try Iron Golem.
I have following items in mind
IK maul ( have 4 of these ) for crushing blow. Should I put eths in the sockets?
Smoke armor. I have 50 allres from summon resist, will this make my golem immune?
Wizardspike. Same question regarding immunities
Insight polearm. But I really don't need mana
Answer the question first: what do you want/need your Iron Golem to do?
Insight is pretty common choice for most necros, and the fact "you really dont need many" makes me feel there is something wrong with you and your setup. Normally you're either constantly drinking pots or have an insight IG around.
I would suggest infinity aura for meleemancer (you can have infinity on both a2 merc and golem slot).
Do you wear beast yourself? Another good choice for IG if you dont hold it yourself for some reason, or have fanaticism from A1 merc.
Eth Doom IG is very stylish IMO.
I see you refuse to use CE with you necro, so you might consider Pride to be good investment for IG, as it suddenly becomes effective again, for non-ce setups.
Smoke will make IG immune to everything except physical damage, yes.
Do note that even if you have the wealth, it is unwise to make a golem out of a Doom or Infinity, because the golem might randomly disappear. It is rare but known to happen. Sometimes you win. Sometimes you lose. Sometimes it rains. And sometimes your golem disappears.
@ughhh: Yes, he will follow you around from game to game. You will only need a new item if he disappears or dies.
It would be nice to know when an IG disapears, i used IG insight since like ladder 4 and i never ever lost one unless he died or i died, it might be just like revives when you cant 'recenter' them with teleport.
I cant really help on that matter but to say i never ever popped an insight IG without having enigma so i usually never let him wander aimlessly if hes not around my 4X minions...
To be frank since i heard about that issue i buried deep in my mind the idea of a beast IG
You also lose the IG when you die.
Another point to know: The IG is recalculated based on the skills you have equipped upon entering a game. So if you prebuffed when creating the IG, it will only last for that game. You would have to leave every game with prebuff gear on.
