[Raedric Quest broken?]

Did you unlock the throne room door? I have also beaten him near his throne but the quest won't complete.

[MAJOR BUG / URGENT: Game won't exit combat mode]

You need a camping item to be able to revive your falled companion, not sure if this is a bug or maybe you get some revive spells later.

Even if you kill raedric you still won't be able to finish the quest.

[Raedric Quest can't be finished]

I have killed all of the enemies on this level, including raedric.

 

The quest simply won't update no matter what I do.

 

The throne room door has a pretty high mechanics skill check, I googled a bit and from what I read its not required to open that door to finish the quest.

 

So I have no idea.
