This is the strongest [Rhino] you can ever build, a real monster, tank over tanks, the strongest build.
So... why potentially? Well, you have to gain buffs from four mods - [Energy Conversion], [Health Conversion] (three stacks) and [Growing Power] BEFORE you activate Iron Skin. To gain even more eHP, you would like to use [Rhino] Charge with augment [Ironclad Charge] to get more armor BEFORE you activate Iron Skin. And your three teammates have to wear [Power Donation] Aura :) But even without [Power Donation] Aura, this is the strongest build.
With Umbra Forma and Helminth Empower ability, you can add [Power Drift] and archive 539% Strength.
This build exists for only one purpose... to check how high can you get with your Iron Skin.
Suggested Arcanes are [Guardian] and Tanker :)
