As I've read, any humanoid mob 39+ has a chance of dropping this book. I know books are very rare drops, but on average how long did it take you to get this book? Last night I spent a good 3.5 hours both in Skathmur and Bail Rova killing Iron Crowns (which I'm guessing is normal), and I'm heading back there tonight to put in another 3. Just curious to hear from others what their experience is getting the books (pages are a different story).
