Great build for SteelPath and long Arbitration runs.

Using both Elemental Ward with cold element alignment (white emissive color) and using Vex Armor will make your damage reduction insanely high. Other players tend you use [Adaptation] instead of [Narrow Minded] but I have found it unnecessary with the ridiculous amount of armor you get from this build and the very high damage reduction.

Molt Augmented is to just overkill everything. You could replace it with Arcane Nullifier if you want to go kill the profit taker orb.

Make sure to recast Vex Armor before the duration expires so you keep the stacked damage and armor bonus.

Helminth Ability

[Chroma]'s 4th is useless so you can change this for any of your favorite helminth abilities. Considering the low efficiency and constant casting of abilities, I suggest you use [Protea]'s Dispensary. It will last for a little over 27 seconds, that gives you the chance to activate Arcane Energize almost twice.

Happy hunting, fellow Tennos!
