Yes
Can you still summon Durnehviir?
Yes
If you can still summon him, does he react the same as he did when he was teaching you words, or does he act like a summoned follower and fly around and attack stuff for you?
He flies around and attacks stuff
A thought that occurred to me is that Durnehviir teaching you words may act like a word wall and you may need to be close enough to 'absorb' the word.
He was practically on top of me every time he was summoned to teach me the words
Using the console sounds like the best option. How do I found out my Dawguard load order?
Thanks for your help!
