bone necroes suck at mf sorry they cant deal that mcuh damage to be good.. get a sorc or a hammerdin for mf

Invis is right, but I did use my bone necro to run all the keys.

I used CE to help me with nilithak, usually I bone prisioned all the minions around him and killed them off, and used a chain-reaction CE to outright kill nilithak. (as long as the bastard didn't tele)
