Need poison necro advice and items!

[Game]

Im using full trag set + death advance + carrion wind x 2 + atma amulet + plaguebringer (all sockets fulled with psn facets).
Obviously, u need a necro torch, anni +3 poison maelstrom and pyb gcs (plus some arcane essences to get nice mana).
Im doing 250k with maelstrom and the revives tanks every monsters, and if there's no revives, golem and skeletons do their job

At least, i can do LK runs in 2 mins and Dreamlands takes a bit more of time.
Time rift is a bit harder, i have to die 3 or 4 times before kill Diablo there.

I might be a complete idiot, but I am 99% certain you cannot get +3 Poison Maelstrom on annihilus!
