Clay Golem Rocks
I'm starting to think a mere 1-4 points into this for any Necro build is a good idea. Heck, just a decent skill item alone should do the trick. It just draws such an insane amount of attention away from you, doesn't die easily and is relatively cheap to recast in the rare event that it does die. It's like an automatic bone wall, really. CG, I love you buddy. Where you been all my game?
