Treasure Trove is one of the powerful rooms in Blue Prince, serving as a major source of Coins during your playthroughs. Each time you draft a Treasure Trove, it adds five Coins to the altar in the room. However, you cannot draft the Treasure Trove by default. It is one of the Found Floorplans, meaning you must first discover the actual floorplan to add it to the draft pool.

The Treasure Trove is one of the challenging Found Floorplans to acquire, as it involves solving a series of puzzles. Leave the worries, this guide explains the complete process of finding the Treasure Trove floorplan in Blue Prince.

Where To Find Treasure Trove Floorplan in Blue Prince

Directing Power From the Boiler Room

The Treasure Trove floorplan is located in a secret area behind the Underground red door. To reach the area, you first need to unlock the red door, which requires power from the Boiler Room. Direct the Steam to the red panel on the wall located right next to the Boiler Room elevator. Powering the red panel unlocks the red door at the Underpass

Rotating the Gear in the Underground Reservoir

To access the Underground area, you need to open the Basement door with the Basement key. Solving the gear puzzle at the Reservoir takes you to the red door. Instead of just connecting the pathway to the Underpass area, your goal is to raise the gear platform above.

Once you raise the gear platform, get to the Underpass side. Activate the switch at the Underpass to rotate the platform, forming a pathway on the upper level platform. It allows you to reach the secret room that contains the Treasure Trove floor plan.

Now make your way through the Underpass and head left to reach the red door. You will discover that the steam from the Boiler Room unlocks the door. Following the pathway eventually takes you to the gear platform at the upper level. Cross to the other side using the gear path. Enter the code ‘May8’ to open the door. That’s it, you will find the Treasure Trove Floorplan placed on a slab to your right.
