I would like to get every creature possible into my mosntrology tome, and I finally got the Animus spell for Onis. However, it seems like I cannot refight the Gurtok Barrier Demon, the mini-boss located in Ravenscar. How can I face him in battle again, so I can complete my tome?
I am trying to finish out my tomes as well. I noticed upon entering the room he appears to be standing there but will not engage. There is, however, in the room a stand that if you move next to it allows you to summon him again and collect animus.
