(Spoilers) I am not sure if this fits within this forum category but here it goes: So I got entrance to Raedric's Hold. I figured that I would kill everything on sight. That I did.. now I am stuck as I think I have killed what I should not (priests). I need to enter a door that have unlock requirements way above my current level. My quest jounal says that I should wear some cloths to look like the priests.. but there are no more priests. I cannot believe there aren't other options. When my barbarian starts killing he only stops when no one else is standing. How can I proceed?
