I like this idea but i think you should have to tak it twice for compnions to use it.
Some companions may know how to use PA already.

I think a better method for getting companions to be PA trained would be to take them somewhere to actually get training, at a large expense of course

~Unless your characters stats made them a capable teacher.
Irreparable has no meaning in a game where you can loot bodies. That is not going away. You all need to accept this and shut the hell up about a fantasy of power armor being ruined beyond use because a hole has been punched in it that magically fried all of its circuits, destroyed all of its servo motors, made the fusion engine on the back explode and take out all intelligent life within a 2 mile radius, caused the physical structure of the armor to crumble into dust when you tried to take it off the body, and does not exist at all except being worn by invincible supermen who will utterly annihilate you if you even look at them funny.
Awh, there you go again. Throwing any indication of being reasonable back out of the window. Im actually just trying to have a discussion about it, just a nice conversation to pass the time. If you're not capable of that then maybe you are the one who needs to "shut the hell up".
How is it back under there by the way?
