Core: Adlet Core (this gives best health stats)
Model: Bhaira (to get Lacerten, just pick any if you already have this)
Bracket: Cela Bracket (this gives most %health bonus)
Stabilizer: Hinta Stabilizer (to get the Synergized Prospectus mod, if you already have it, just pick the one you like the most ^^)
^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.
