Salvation's new trick

[Crystalion]

I'm thinking about making a necromancer designed entirely around supporting an iron golem.

Wait until v1.10++, is my advice. The Iron Golem will vanish on you, just because you walked a little ways and didn't realize its pathing was stuck (mercs don't have this problem--they warp--so I know blizz could have fixed this if they considered it as serious a bug as I do).

I've always loved toying with Iron Golems.

Perhaps your build idea would be less frustrating in sp, where either the item or the whole char save could be restored when a game misfeature (politespeak for "bug") eats your golem.

Note my post reply on the 20/50 poison resist issue however, as I may have some tainted results when I tested things.
