The parts chosen to build this Hound don't really matter. The stat differences are minuscule and Sisters have random Hound configurations.
Bhaira, Raiju, Urga, and Hinta is the suggested combination if you don't care how they look.
Precept mods have a priority system as shown in the following picture, with 1 being the highest priority and 10 being the lowest priority.
Precepts are placed in their current spots to ensure they're used in the most opportune times. Do not change their positions unless you're confident in how these conditional mods are activated by your companion.
