Use blood golem and iron maiden always! You don't need other golems even though they are stronger. That point will be better used to make advanced skills (like bone spirit) stronger. Don't waste a single skill point on something you won't use in later levels. Bottom line: If you are going to use your necro in nightmare or hell modes, you gotta think ahead. The monster level upgrades for each of the game play modes (nightmare, hell) makes this a ridiculous claim. I have read those other strategies and some of them make sense, but some just suck! You can't take advice from a level 20 something necro who claims they beat Diablo in Hell mode! It is impossible. To all you wanna be necro's out there: For life beyond D2 normal mode, you gotta think ahead. in act 5 there are some great heads, but if you cant get one trade. Also use bone spear or spirit for a pimary attack.
this will heal u and you dont even have to fight! this is great against Diabl. If u like blood golems than use life trap in conjunction.
