After some early patches of Skyrim, I've not seen any more Draugr Death Overlords with the Disarm shout. Did gamesas remove these from the game because they were too over-powered for low level players? Just wond'ring.
Idk, maybe they only use it when you get to a higher level. Hasn't happened to me in a good while. Btw that's one creepy @ss picture. Just sayin. I'd crap my pants if I ever met your character.
They stop using them once you grow too powerful for them. I think the level cap for Disarm to become ineffective is 30, so if you passed that, they aren't going to try to use Disarm on you anymore.
