So I'm trying to complete the deed "Ringlore of Tham Mirdain". I've run School and Library over a dozen times each, and the Ringforges of Tham Mirdain six times, but the Aged Manual of Ring-lore just wont drop.
Has anyone else had an issue completing this deed? I believe it is supposed to drop from the Ringforge of Tham Mirdain, but have run them all just to be sure. Regardless, it has not helped.
