Does anyone know where to find the door with two obelisks? The picture in the spellbook quest page showed a door that looks exactly like all the doors leading to a boss. But none of them have obelisks!!!
You may have already realized this since you posted, but I was also having trouble finding the door with two obelisks--until they appeared when I got close enough. On my computer, I hadn't seen them until I got fairly close. So if you are looking down the corridor at a door and don't see them, get closer to really check.
