backup for poison necro? What's a good backup skill for a pure poison necro? I'm building one like this: 20 poison nova (main attack) 20 poison explosion (synergy) 20 backup?? I looked at bone spear or bone spirit but I'm nto sure they will do enough damage. So I'm thinking corpse explosion. That should be viable huh? Also, is it possible to play with 1 point (or at least few points, with +skills items) in golem and no other minions? Can an iron or fire golem survive around 20 seconds in act3/hell? If a low skill golem isn't viable, how about mid-skill (slvl 10ish) bone wall?
