Also, you can socket your helm and shield with poison facets to increase poison skill dmg and decrease enemy resist. Not sure I would do the 3 soc helm and th 4 soc shield all stuffed with facets. And I'm not sure I would wear Bramble if I could get an Enigma. But that's just my preference (love the tele )
But Deaths Web is by far the best weapon. Get it if you can afford one. They are expensive though. And no reason not to use Trang Gloves...they're cheap.
Re: What are all the good poison gear items out there?
3 piece trangs (gloves and shield are a must). Gloves give +25% pdmg and shield has a partial set bonus of -25% epr. The third item used is usually the belt. Of course you can skip this and use something like Arach + Homunculus (especially if you have a nice Dweb)
Shako (of course you COULD find a +3p&b 3os one and socket 3 perfect poison RBFs...)
Bramble gives a nice poison boost, but Enigma, CoH, or even a good SotV or Skullder's will be a more balanced choice
Anyway, in my eyes the must items are Dweb (because of the massive -epr that softens up broken immunes) and trang gloves (because it's easy to get and can't get anything remotely as good for the glove slot). You can customize the rest of the stuff as you see fit to account for survivability and more comfortable gameplay
