Suspicious Book

This treasure is located in the Undermine. To find it, head to the coordinates: /way 48.18, 65.35. There, you will see a metal staircase leading up. Climb it, and you will find yourself in front of a building. Go straight and enter inside.

To your left, there will be a metal bookshelf at the coordinates: /way 49.90, 66.13. On the shelf (carefully hidden between the books) lies a magical book. However, as soon as you try to pick it up, the book will disappear. Despite this, the treasure icon will remain visible on the map.

Next, go up to the second floor of the building. There, at the coordinates: /way 49.54, 64.54, you will see another metal bookshelf. The book will reappear inside the shelf, on top of other books. Interact with it, and it will fly away again, this time to the third floor.

Climb up to the third floor using the metal staircase. There, at the coordinates: /way 49.80, 65.65, the book will be lying in the middle of a desk. Interact with it one final time, and you will receive your well-deserved reward (trinket) for your efforts.
