Auramancer Life Based EK - Theorycrafting In Progress

Hi, I believe this is my first post in build/class section

I'm currently theory crafting a Life Based Auramancer EK build suitable for both party and solo playstyle.

Currently Planned Endgame Passive Tree

I'd really like constructive criticism and input on the tree so that I can finalize the build and make a character and create a real guide

Core Items will be

Prism Guardian
Alpha's Howl

Core Skills will be

EK with relevant Support Gems (Of course)

Pretty much all Aura Gems

Planning to get dps out of Ele dmg from auras and critical (though I'm having really hard to trying to find a way to fit crit nodes in)

Lifewise, we're looking at at least 200+ so it should be fair in terms of surviavability

Any input would be nice and helpful thank you
