The Book of Mysteries is a power book that can be obtained by opening either Mystery Boxes or Golden Mystery Boxes. The chance to drop the book starts at ~1% for Mystery Boxes and ~2% for Golden Mystery Boxes, and it increases by 0.04% for each of either box opened until it is dropped. Then, the chance stays at ~0.5% for Mystery Boxes and ~1% for Golden Mystery Boxes. It cannot drop from Mystery Boxes until the player has opened more than 10 of either type of box.[1]

The first reading grants the player a power that increases the chance to get Mystery Boxes or Golden Mystery Boxes (after claiming Foraging Mastery) by 33.3% in all situations with a random chance of earning a mystery box.[2] Once read, it can be found in the Player's Menu on the Special Items & Powers tab. Each subsequent reading gives the player 20 XP in each of the 5 skills.
