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.

Major Change:

• Dendrobate + Darkness Enthroned for 100% minion Poison Chance

• Anamamus Gaze do add some dot-multi for the crawler

• tempchains for poison duration

• Corpsewalker boots to have a guaranteed corpse nearby (Plaquebringer)

• Eldricht Battery to solve mana

• Aspect of the Crab for additional physical damage reduction

• Animate Guardian for Fortify, Culling Strike and additional Chaos Damage

• 3 Buff Spectres (Grace, Malevolence and Haste or Onslaught)

• new Greater Fork Support instead of Pierce for better Clear and more returning projectiles

• new Cooldown Reduction support for Convocation and Molten Shell

• Rational Doctrine + Bitter Hersey (Lycia) for Chaotic Might (optional)

Overview:

• Up to 30 million Shaper-DPS

• facetank any Standard-Content, can take on T17 & Ubers

• can deal with almost any Map Mods and League Mechanics, Alc&Go

• Immune to Elemental Ailments, Corrupted Blood, Crit, Bleeding

• 100% Spell Suppression

• 80% Physical Damage Reduction

• 80% Max-Res

• 75% Attack Block

• 55+% Spell Block

• 70% Evasion

• Permanent 10 Fortify

• Permanent Onslaught

• 64 Life on Hit with dozens of hits per second

• Automated, permanent Flasks

• No expensive mandatory items

• Easy to play, ranged or close up, damage continues while moving

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
