Hmm, i've never played a boner, but I do have a poison necro. He uses full trangs, marrowwalks, +3 P&B skills amulet, (don't remember rings) and FINALLY a Death's Web wand. And he does not own hell. In fact, Act 4 is Hell for him. Killing boss's is also tough with a poison necro. I put one point into my skellies and let +skills to the rest... and 1 point into revives. This gives me good meat shields, but with 1 point into each curse, 20 into nova, explosion, and dagger, the 1 point spells like bone armor and CE... and I put one into spear to see how well marrowwalks would help it... there is really not enough points left to make ANYTHING powerful after you fully synergize your poison spells. So I can do areas with non poison immunes great. I spend a lot of time throwing up bone walls, curses, and hiding behind my revives/summons... but when it comes to areas with poison immunes, it's tough (try act 4 with poison necro in hell).. and boss's... let's not even talk about boss's with a poison necro. Show me a poison necro who can effectively deal with Listers pack and I will be suprised. Not to say poison necros aren't a blast, but I would NEVER suggest one to somebody who plays mainly solo and intends to finish hell. Maybe other poison necros will say differently, but that's been my experience.
