i dont know, he was pretty weak and died before an actual fight started
i wouldnt worry so much about it, you're not gonna get some epic bossfight anyway
I was trying to make him a summonable creauture when I noticied this. I thought it was something I did wrong but youtube videos prove otherwise.
Well so much for epic boss fight or epic summon for that matter. Still it seems buggy like he's not supposed to fight like that. I tried changing his class and ai data to Draugr melee but still same behavior.
