Why this build ? To create unbreakable snowglobe and strip all armor in steel path with 1 cast

The calcul for the snow globe is bassed in majority with your base armor and ability strength, so elemental ward (cold version) multiply your base armor proportionally with your ability strength, so push "2" push "3" for an imbrakable snowglob, in bonus your "4" strip 231% of armor

Snowglob health = (Base Health + Armor Multiplier × ([Frost]'s Base Armor × Base Armor Bonus + Additional Armor)) × (1 + Ability Strength) + Absorbed Damage
Base health = 5000, armor multiplier = 19, [Frost] base armor = 300, base armor bonus = 5.78, additional armor = 744 (i'm not 100% for this one), ability stength = 3.85
So 252 597.7 health per "3" spam while elemental ward is active.

With molt augmented you gain +60% in ability strength (after 250kills, no time up) and +900 armor with arcane [Guardian] wich pump up the armor strip to 267% and the health of 1 globe to 464 645.2 hp
By the way 1 000 000 health is the max you can achieve whith multiple globe.

You can replace [Stand United] by [Growing Power] or anything that suit your taste.
You can replace [Power Drift] by [Coaction Drift].

I don't think that [Archon Flow] is worth a forma (with this build)
If you have the luck to have the arcane squall helmet, just put it and say goodbye to arcane guardian (+15% ability strenght, -5% shield)
