Noob question about modding perks and NPCS

[somulo]

Hello everyone, I'm new to the modding scene, and for the past week I've been working on a gameplay overhaul and rebalance mod. So far most of it is working as intended but I can't figure out a good way to implement changes to the way power armor behaves. Specifically, I tried attaching perks to the equipment as enchants, that would modify incoming damage values and the power armor damage multiplier to that specific body part as long as the piece was intact, with some exceptions for specific weapons and damage types. The goal is to make it so that power armor makes someone virtually invulnerable until the armor is compromised. If there's a much better and more efficient way to do this, or If I could just apply the perk to all humanoid actors en masse without having to do it on an individual basis, any tips would be greatly appreciated.

 

I tried looking at existing tutorials and documentation about the "gethitlocation" condition, but all I found was that it was marked as an obsolete function back in the Skyrim version of the CK. When I applied it to the perk it doesn't list any body part identifiers under the parameters dropdown list, but I can change the numerical comparison value. What I would like to know is if there is somewhere I can look to see a list that might explain what numbers correspond to the correct body parts on human and ghoul actors, or if this condition is still nonfunctional and I'm just wasting my time.
