Why Arcane Battery?

This new arcane needs ~3333 Armor to fulfill its full potential which is +1000 maximum energy. Its existence just shouts "[Chroma]" at my face because [Chroma] is THE warframe to casually achieve 3333+ armor and maintain it. Also, high strength [Chroma] need a lot of energy. This arcane just fits so well.

With the build above and without any external modifier, a 1043% armor bonus means 5144 armor and 94.49% DR. We have 1855 energy with 2.4x efficiency from QT, and extra 90% DR from [Adaptation], resulting ~800k Effective HP from Energy alone. Still can't tank a 1m hit, but more than enough for daily casual play.

Essentials

We need about 741% Armor bonus for Vex Armor to get 3333 Armor, so that's ~212% strength which is too easy for an ordinary [Chroma]. We just won't stop there.
[Blind Rage] + Transient Fortitude + Umbral Intensify the good old three strength mods are basically already on your Chroma if you ever main-ed him in the past.
[Archon Intensify] has better numbers but a pain to actually use since it only triggers on [Guardian Armor] heals.

[Guardian Armor] is a huge QoL augment for [Chroma], you will never run out of Vex Armor if been given enough mobs to kill, a must have for daily use.

[Adaptation] is a must have for health tanking frames.

[Primed Continuity] to boost Vex Armor to ~32 seconds, which is a long enough duration for you to get some energy and refresh it when mobs are not enough for [Guardian Armor] to upkeep.

With such a huge Energy pool, we can have [Primed Flow] + [Quick Thinking] to both health and energy tank.

Flexibles

PSF is just so good. If you don't have it, anything else is fine.
[Combat Discipline] + Arcane Avenger for more crit. [Growing Power] + Molt Augmented for more strength. [Brief Respite] for more shield gating. Arcane Energize for EVEN MORE energy. You name it. Just anything you like.

Get rid of Effigy

This is not a Profit Taker build so Effigy is useless. Helminth it asap with literally anything.
