I don't actually know how it works. Can they be knocked over a certain amount of times before it's fatal, or do certain enemies just attack them while they're down to kill them?
I actually don't want any more Companions to accompany me, in case they all die and can't give me quests anymore.
From what I've been able to deduce, companion characters cannot be killed by NPCs, only incapacitated.
What
can happen however is that your AOE attacks can hit them while they are incapacitated, and that's what actually kills them. If you just stand there and let your companion do their thing, eventually they will win. Guaranteed. The problem is you surviving that long.
What's
really annoying is when I use Storm Call to try and hit a dragon to get the stupid thing to agro, all of the lightning hits my companion. For whatever silly reason, dragons are apparently immune to Storm Call and can't be hit by the randomly targeted bolts of lightning.
