Power Charge Stacking Chaos Spellslinger

Hello everyone,

I was tinkering around PoB for a few days and came up with a kinda interesting concept which is possible due to the new buffs of the chaos spells and specifically the projectiles of the transfigured gems of Soulrend and Essence Drain from 1 @ all gem levels to 3-5. I've made a video about it.

There's also a Starter PoB https://pobb.in/KuMslcYUuw8H here.

What I would ask is for some ideas and/or suggestions to scale this to the endgame. One of the few things is going for Gem Levels and Spell Rage helmet that drops from Uber Eater. I have some ideas floating around with Impresence to use 2 Free Auras which via the Doedre Scorn helmet will give us a lot of flat dmg. Depending on how vestigial uniques work and which modifiers we get, I might also use the Uber eater rage helmet to enchant Doedre's scorn.

Had some ideas also to use Whispers of Infinity to make my mana costs be my energy shield which would solve a lot of problems and would let me add Forbidden Rite of Soul Sacrifice as well.

Curious to see/hear any takes on this!
