This is an alternate iteration of the quite successful champion-version, which is still very playable or even better with the new tools at our disposal.

But instead of just tuning some gear and tools, I decided to mix things up as necromancer and go all in on chaos & poison.

Sidenotes:
the expensive Stuff is not necessary, even for ubers.
You are perfectly fine with a life flask instead of Progenesis
The annoying Perfect Forest Tiger is completely unnecessary; it is impossible to see how many frenzy charges the crawler would gain on average. Just take the onslaught spectre.
Rational Doctrine + Bitter Hersey can be replaced with Corpse Pact (15% Shock), Void Beacon or even Commander of Darkness if you struggle with resistances
