Archon shards = Strenght + Maybe 1x tau into shields for abit more baseline ehp. + 2 Cast speed Because u will only spam 4. ability pretty much and the cast speed is really bad + 1-2 Energy orb effectiveness (Optional)

Very nice to stay immortal / upgrade ur melees dmg further & to do defense / Interception

Arcanes can be : Molt Augmented / Arcane Energize / Generic Dmg arcane of ur preference.

We are buffing our party with up to 50 000 overguard + 200% crit and 250% crit dmg with Biting frost + Cold status effect + + AoE constant Armor strip & general Freezing+ Can carry defense / Excavs.

Use [Rolling Guard] when ur overguard breaks & recast 4. ability while immune. U can also cloak stealth in operator if in extra big trouble.

''U can technically also skip [Rolling Guard] & play with the Cold dmg augment for ur Squad'' If u prefer that :)

[Primed Redirection] mostly there as an EHP booster for EDA & Melee Retaliation Arcane scaling. Melee Retaliation is alot ahead in melee scaling than the other arcanes especially for pure slash melee setups.
If U dont want extra shields underneath ur overguard or play melee retaliation u can play the 3. Frost Syndicate mod that grants ur party Cold dmg on weapons instead :)

Insane melee Build for Frost / Shield users = https://overframe.gg/build/627236/

Best Subsume if u wanna make this ur Melee Retaliation Scaling Frame = Nourish for Added Free Viral on top of ur Massive Slash & Toxin melee setups.
Breach Surge is also extremely good to cast as it scales dmg from ur [Biting Frost] dmg boost aswell.

Very tanky and smooth to play ;)
