Inspiration for this build is taken from Taurael's Tanky Slow [Nova] and it let me solo almost all of steel path with no issue. Reasons for mod selection where they are the same as Taurael's build is the same as their reasons, 2 umbral mods for 110 more hp and enough power strength for max slow from molecular prime.

[Handspring] stacks with [Constitution] and is invaluable to me since I mainly use melee and [Hate] getting knocked down, all my builds if it isn't on a warframe that can [Negate] knockdown I either use [Handspring] or primed surefooted. [Adaptation] is great for extra survivability especially with the overshields you get from pillage.

Pillage and molecular prime go together like eggs and sausages making anything you're fighting unless it's a sentient completely helpless and turn to [Ash] with the slightest poke. Swap out [Corrosive Projection] for [Energy Siphon] if you aren't using Zenurik, you can use any arcane combination you want these are just what I normally use.

I put this up here for a friend who wanted to get my build if anyone else ends up trying it out I hope you enjoy it.
