I'm running into some problems with my followers' armor rating. I'm running UFO, and when I check their stats, their damage resist is more than -1000.

I'm also using Cloaks of Skyrim, and ASIS. Not sure if those might have an effect...

Basically what I'm looking for is a way to forcibly change my followers' Armor Rating. I've tried the console command force av DamageResist , but I can't seem to find the right target for each of my followers.

"RestoreAv DamageResist 1000" or some other large value.

Yep, this often happens when you shout Marked for Death and it hits your follower rather than your opponent.

The console command as mentioned above will restore the stats - put in a large number like 1000 or even 10000 - it'll only ever restore back to the max they were before in any case.
