make them craftable with Armorer[3]
problem is, they will require lots of mats, so many that they will be too worth to wear anyway (unless someone dont care to waste)
mats: 3 oil cans (those which one guy in APA in F2 asks to use on him cuz he couldnt move)
25 HQ alloys, 10 good metal parts, 5 electronic parts (power armor is made with some inside electronic mechanisms), 50 (or 100) MFC (not sure, but i think its operated on them)
requirements: power armor will require skill of repair to be 250%(?)
9/10 ST, and 8 perception for "careful creation of high tech power armor" because it has all those little details which need to be made correct, like helmet, legs, arms, they all in metal, and they gotta move as smooth as possible, otherwise arms/legs/neck start jamming, blind man cant make good armors, thats why i put 8 perc.
dunno what else to add, but in my opinion this is good for creating PA, much stuff to spend to create it. cooldown could be 120 minutes.
