My version of THeMooN85's build. seen here:
https://overframe.gg/build/59179

I went with [Negation Swarm] instead of [Sure Footed].
I also swapped [Primed Vigor] for [Vigor], since I do not have [Primed Vigor].
This allows me to max adaption and reduce the forma cost by 1.

You can also add a forma on [Negation Swarm] and upgrade [Umbral Intensify] a bit.
(if you want [Primed Vigor], forma the [Negation Swarm].)

I also think the [Rejuvenation] Aura is better for this build but Swap to [Physique] for an extra 700ish HP.

I am using the [Deconstructor Prime] with 3 gladiator mods, and a [Life Strike] Heavy attack melee build.

The umbral forma version of this mod would allow you to max Intensify and to use Primed Vigor if you have it. See it here: https://overframe.gg/build/59376/
