For my Khora Prime Build
Core: Raiju Core
Model: [Dorma Hound]
Bracket: Urga Bracket
[Stabilizer]: Frak [Stabilizer]
^This combination allows for the highest health and armor.

[Shield Charger] or [Primed Animal Instinct] (You already have the latter on [Venari], if using my build Link BUT they do stack, however, we are running out of mods here, and you don't need 2 of these.)
I wish there were space for [Metal Fiber] too, maybe instead of [Guardian], but the hound will heal with your Whipclaw anyway, so it shouldn't be needed.
