Choose the puzzle you are working on, check the items already in your inventory and reveal the solution when needed. Checkboxes record preparation only; the room’s state still matters.

Opening seal

Hint: The book’s three clues describe ingredients and an environment.

Items to prepare

Show solution

Combine the developing chemical with the blood obtained during the bathroom mirror interaction. Let sufficient sunlight reach the mixture by dealing with the boarded window, then use the resulting mixture on the sealed study door. This is an in-game ritual, not a real chemistry recipe.

Develop a photograph

Hint: A roll, a negative and a printed image are three different stages.

Items to prepare

Show solution

Fit Red light bulb before using the developing tank. Develop the roll, put the negative and photo paper into the enlarger, and print the image. Fill the trays with the developing chemicals and process the printed photo. If the image is not yet visible, the process is not finished.

Restore the memento

Hint: The display box is missing its figures.

Items to prepare

Show solution

Combine the two figurines with the glass box. Examine the completed memento, then return to the matching bedroom scene. Do not confuse an incomplete box with the finished object.

Purify an enchanted object

Hint: The book asks for three sources of water, not one.

Items to prepare

Show solution

Fill the silver bottle from three emerald bowls, then expose the filled bottle to moonlight. Use the purified water when the relevant enchanted-object interaction becomes available. A bottle with only one or two doses is not ready.

Power the phone

Hint: A cable alone cannot be plugged into the wall.

Items to prepare

Show solution

Combine the USB cable and adapter into a charger. Use it at the phone’s charging interaction and read the available messages. Return after the story changes: some information is deliberately obscured earlier.

Complete the Aurifer

Hint: Preparation and transformation are separate tasks.

Items to prepare

Show solution

First obtain the Lapis Fictus blade. The old book then specifies electricity → mercury → moonlight. Use the kitchen’s electrical interaction, the mercury in the deepest room and the appropriate moonlight scene. Check the blade’s changed name after each step.

Hidden Bible route

After Endings 1 and 2, a fresh run adds a Bible. Its three optional interactions award the Iron Crosses needed for Ending 3 and can be missed if the nearby ordinary puzzle is completed first.
