Does the new Bard enchante that keeps moisture off instruments also work on spellbooks? If not, will it in the future? Would be nice if that was another way to keep moisture off the spellbooks (heck, textbooks too).
They do. There was a crystal you could get for your spellbook called a hafaltu-veined kuldaez crystal. Put it in one of the slots and boom, waterproof. Well, not permanantly, but then again, what is?
