Finally made this kid, everyone kept saying he was awesome. Here's my hot take. I have to say, the Umbral format looks good on this dude. Very much a boss frame, I don't know what kept me from taking a crack at Revenant Prime but I enjoy him. I feel like I got a happy place with my build while coming in at 484% for Mesmer Skin/434% for the rest of the kit, after 250 kills, [Mesmer Shield] 50% bonus, and [Growing Power] Proc if I did my math right and there isn't a cap.

UPDATE:
Now that I have used it more, I like it a lot. Tbh, at this point doing the math and even if I could squeeze a little more [Juice] out of this build I think is negligible. I found Thrall Pact, it has quite a bit of contention. So far, I can manage to keep 1-3 thralls up even in a group setting. What I found is that power strength affects this augment. So at any given time a single thrall can give you a decent power boost and in solo it goes hard af. So I'm going to burn the forma and throw the second augment on. When I get some yellow shards and update this later, I am using [Natural Talent] in place of range.

I didn't notice the range much when I was testing the different augurs and [Natural Talent] being that was my flex spot kinda. I also looked at a bunch of other builds and I noticed I'm the only build (as of posting this update) that has the slot to spare and reaches similar results. Because if you've seen my builds before I always want the hp...because my reaction time is a little slow. I feel like I'm the only one that gets insta-killed by any status ailment while my squad mates are reacting fast enough to do something lol. So having the option for an occasional boost in damage sat right with me.

It shouldn't be hard to enthral one or two enemies when the Acolytes show up. Once your focus is on them you're up to 7, charged with more f u than you know what to do with then delete that ass.

That's my hope.

UPDATE v2:
After talking to my clan mates about it, it was a niche application for getting out of sticky situations because of the low cost of enthralling with the Zenurik Operator ability being easily able to get that far. But they assured me I shouldn't really ever be caught like that unless dealing with nullies. I scraped it since I'm only ever that deep for the same niche reasons lmao. So I went with [Equilibrium] with Panzer...you know the drill. Infinite energy in the most insane way possible.

I'm keeping the update up for proof of concept that you can drop [Equilibrium] for [Thrall Pact] if you wanted the shenanigans. You can totally drop Arcane Energize as with [Equilibrium] and pet you have infinite energy. I frankly don't have many Arcanes outside the basics. I'm still MR 21 at the moment of this update and I'm just enjoying the game and making builds in this chapter of wireframe.
