Theorycrafting - Necromancer of Bad Ideas

Bad ideas include Trypanon and Elemental Hit in the same build. What could go wrong?

Short version - use Trypanon with Elemental Hit to cast-on-crit Summon Raging Spirits and get as much increased duration as possible on Immortal Call by taking every plausible increased duration node.

(Overload and Equilibrium are iffy - not sure on the mechanics and the numbers)

6L body would be:

Elemental Hit, Cast on Crit, Summon Raging Spirit
Multistrike, Empower, Faster Attack Speed

Ideally placed in +2 Skin of the Loyal for maximum silliness. Trypanon's damage is lousy, but we don't care because elemental hit (at level 28, more likely 26) is what we're actually using to hit and we're spamming out level 28/26 raging spirits.

The 6L on the weapon would be:
CwDT, Immortal Call, Flesh Offering, Blade Vortex, Increased Duration, Efficacy

Somewhere else in the gem slots would be a CwDT Desecrate for corpse generation, haste, vaal haste, a curse (maybe Warlord's since we don't have leech otherwise), leap slam for movement, and maybe arc or something to generate the initial power charges before vortex is triggered.

It would use Romira's Banquet/Voll's Devotion/(Inya's Epiphany maybe) to constantly generate endurance charges, all used to increase the duration of Immortal Call with a hope of keeping it up a substantial percentage of the time as a defense since we have so much increased effect duration. A +1 to max endurance charges belt would be ideal here, since we have more max power charges than endurance charges. Banquet will generate power charges from the blade vortex hits, since all of our melee is critical.

We'd have a helmet, one ring, a belt, and gloves to get resists, life, and the other usual stuff. Jewels would be attack speed and life and cleanup on resists.

Since this build is crazy expensive to set up (10+ ex for just a +1 skin of the loyal, L4 Empower, and a Voll's), I want someone to tell me it won't work.

An alternate version might be to use a +3 to fire gems bow, pie-in-the-sky version one with innate Cast on Crit from Shaper affix to free up a gem slot. That would move the CwDT 6L to the body, which could be just about anything (maybe Belly for some life) and drop the need for Blade Vortex.
