Basically the most endgame-viable Umbra you'll get. Use white on your emissive to get the juicy 437% armor bonus.
If you're worried about the dps of [Exalted Blade], use a [Kuva Nukor] with a lot of status to put [Condition Overload] and [Healing Return] to max use
you'd also want to use naramon focus and a deconstructor equipped with weeping wounds and gladiator mods
Even you want even more survivability dw I gotchu;)
switch out Brind Rage for Transient Fortitude
