This is a build I personally made because I felt like [Khora] should be a dominating and controlling force on the battlefield.

Most build just make her look weak or like a tool, but this build truly makes sure that you're one of the last Tenno standing on the field.
She's meant to control and shut down the enemies.
Place her cages at choke points.

And look at that tasty armor. 708 before any conditional effects start kicking in.
4831 with conditionals.

This build specifically has a stronger emphasis on going for melee. (Steel Charge is a must-have for this build any way, otherwise the capacity won't be enough. At least not like I build it)

"Downside" is that you can't really max out the Umbra mods.
So if you did that, you're out of luck with this build.
(UNLESS YOU WANT TO USE UMBRA POLARIZATION)
You could obviously also switch them for their non Umbra parts.

You could switch [Vigor] for [Adaptation] if you really wanted to.
Arcanes are obviously optional. Use whatever you think is best.
I think Strike and [Guardian] if you really want to armor up, otherwise you can use Strike and [Fury].
