How to Get the Applied Esoterica Badge in Peak

By Ambar Jimenez | 2025-11-10 20:53:39
The ROOTS update for Peak has introduced a wealth of new content, but few secrets are as intriguing—and rewarding—as the Applied Esoterica badge. This coveted achievement is tied to the mysterious Book of Bones, a powerful mystical item that bends the rules of life and death. Earning this badge requires a specific set of actions, a bit of luck, and a cooperative team.This comprehensive walkthrough will detail every step you need to take, from locating the elusive Book of Bones to performing the ritual that grants you the badge and its accompanying cosmetic prize.

Finding the Book of Bones: Your Key to the Afterlife

The first and most RNG-dependent step in your journey is acquiring the Book of Bones. This single-use mystical item cannot be purchased and must be found during a raid. Your primary targets are two specific loot sources within the new ROOTS biomes:
  • Ancient Luggage: This is your most reliable source. Search every piece of ancient luggage you come across; the Book of Bones is a potential random drop from these containers.
  • Ancient Statues: These statues can also yield the book, but with a critical condition: every player in your squad must be alive for the statue to have a chance to drop a mystical item. If a teammate has already fallen, statues will not yield this precious artifact.
Persistence is key, as securing the book may require multiple expeditions into the dangerous new biomes.

The Power and Peril of the Skeleton Form

The Book of Bones holds a paradoxical power. It can be used on a fallen teammate or on yourself, each with significant strategic consequences.Using the Book on a Teammate: This is the action required for the Applied Esoterica badge. It resurrects your ally, bringing them back into the fight as a skeletal warrior.Using the Book on Yourself: If no one else is dead, you can channel the book's energy on your own scout. This transforms you into a skeleton, a state with distinct advantages and dangerous drawbacks.

Skeleton Transformation Effects:

  • Advantages: You gain total immunity to a suite of debilitating status effects, including Hunger, Burn, Frost, Poison, Sleepiness, and Spores. This makes the form exceptionally useful for traversing hazardous environments like the CALDERA's lava fields.
  • Disadvantages: This power comes at a grave cost. Your skeletal body is incredibly fragile, taking double the usual damage from falls and explosions. Your stamina and carrying capacity remain unchanged, but one wrong step can shatter your run instantly.

Step-by-Step: Unlocking the Applied Esoterica Badge

Follow these steps meticulously to secure your badge and reward.

  • Assemble a Co-op Squad: The badge can only be unlocked in a cooperative multiplayer session. Solo play will not work.
  • Secure the Book of Bones: As detailed above, scour the ROOTS biome by looting Ancient Luggage and Ancient Statues (with a full, living team) until you find the book.
  • A Teammate Must Fall: For the resurrection ritual to be possible, one of your teammates mustdie during the raid. Upon death, their body will appear as a skeleton on the ground.
  • Perform the Resurrection: Approach your fallen ally's skeletal remains. A prompt reading [Teammate's Name]'s Skeleton — (E) Revive? will appear. Hold your interact key (default 'E') to use the Book of Bones and begin the ritual.
  • Claim Your Reward: Upon successfully reviving your teammate, you will immediately receivean on-screen notification confirming you've unlocked the Applied Esoterica Badge. You will also be granted the Skeleton Top cosmetic item for your scout.
  • By mastering the esoteric arts of the ROOTS update, you can achieve whatfew scouts have and proudly display the Applied Esoterica badge as amark of your dedication and teamwork.
