This build is focused around stripping armor and gaining overshields with Pillage while using the [Icy Avalanche] augment to keep yourself protected in a coat of ice and damaging enemies. The other 2 abilities can still be used of course, but they are not the main focus of this build.

As for weapons, you might be wondering why everything uses radiation damage. It's because this build makes use of the [Rakta Dark Dagger], which restores shields and grants overshields when used on enemies effected by radiation. As if Pillage wasn't enough. Additionally the [Kuva Nukor] is there for some extra utility. Also, Deth Cube Prime is modded with the [Shield Charger] ability, which when activated: Increases max shields by 60% and Shield [Regen] by 60% for 10 seconds.

I suggest running either zenurik or naramon. Zenurik for energy, Naramon for melee combo.

So, as you can see, this build turns [Frost] into a damage dealing shield tank, capable of running high level endurance missions for long periods of time.
