First, they took the entire 320-page adventure and broke it down into six slim paperback volumes — one each for the game’s major chapters, plus an appendix so you can keep track of things like trinkets, creatures, magic items, and unique spells. Shredding the book in this way is a great method for helping harried DMs to stay focused on what matters during a given play session. It also helps prevent them from having to lug an entire hardback volume around every time they go to play.”
