The Book of Bones is one of the most intriguing mystical items you can find and use in PEAK, and was introduced with the ROOTS update in November 2025.
This item is single-use only and offers a unique and powerful mechanic that allows you to revive fallen teammates in a different avatar. You do need to have a bit of luck finding the Book of Bones, as it randomly spawns in Ancient Luggage and Ancient Statues scattered throughout the biome.
