Power Hammer
Spoilers Ahead
This page contains spoilers for the Workshop. View at your own discretion.
The Power Hammer is a special item in Blue Prince. It is a contraption that improves upon the basic functionality of the Sledge Hammer, allowing it to also permanently demolish certain walls.
How to obtain
As a contraption, the Power Hammer can only be obtained in the Workshop by combining the Sledge Hammer, Battery Pack and Broken Lever.
Usage
The Power Hammer is an upgraded Sledge Hammer and retains all of its uses, such as opening locked trunks. See Sledge Hammer#Usage for more information.
Additionally, the Power Hammer can be used to break walls and other structures in certain locations, revealing secret chambers and/or information. Power Hammer destruction is usually permanent.
Spoilers Within
This section contains spoilers for breakable wall locations.
The Grounds
In the central area of The Grounds down the stairs, there is a doorway boarded up with wooden planks that can be broken with the Power Hammer, leading to the Sealed Entrance. There is a second breakable wall connecting the Sealed Entrance and the Basement.
These two walls can be broken from either side, and will provide permanent passage between the Grounds and the Basement once destroyed. The state of the planks is what determines whether or not the destruction is permanent; if just the Basement wall is destroyed, it will respawn on the next day, whereas if just the planks are destroyed, neither side will respawn even though the Basement wall was never demolished.
Weight Room
In the concave corner of the Weight Room, part of the wall is weak. Breaking this wall opens a small room with a south Antechamber Lever, a memo, and a fragment of a map of the Basement.
Greenhouse
The left wall of the Greenhouse contains a weak portion. Breaking it reveals documents and a door to draft from. It also makes Greenhouse no longer count as a Dead End in future days for the purpose of the number of dead ends drafted.
Secret Garden
At the right side of the Secret Garden a weak portion of a wall is seen. Breaking this wall reveals a third valve that can be used to turn the remaining weathervane.
Freezer
The frozen wall at the left side of the Freezer can be smashed using a Power Hammer, granting access to the document and Upgrade Disk behind it.
Unlike other breakable walls, this breaking is not permanent and needs to be redone every time, although there are other ways to remove this wall.
These locations may be infeasible to reach with the first Power Hammer a player obtains:
The Precipice
In the chess room, there is a crack on one of the right pillars. Using the Power Hammer on this crack opens a message written on the wall behind it, a 3x6 grid of blanks with the left six having "CASTLE" filled in.
A hint for this location can be found in the Safehouse.
Crate Tunnel
In the Crate Tunnel, once all the crates have been cleared, the fourth door in the sequence of doors is actually a breakable wall on the right side of the room.
Interactions
- The Power Hammer may be stored in Coat Check or retained with the Moon Pendant like any other special item. Starting the day with the Power Hammer in Coat Check, or with it already in the inventory due to the Moon Pendant, will cause the Sledge Hammer to be unobtainable today. The Battery Pack and Broken Lever are unaffected and can be obtained like usual.
- [Mail Room Experiment Spoiler] The Power Hammer is referred to indirectly in Randolph's twelfth letter to the Mail Room in the not-so-mysterious hint, "Break the bricks in the Weight Room with something that has a handle and is very heavy."
