👣 The Definitive Critical Path (All Maps Integrated)
Phase 1: The Flooded Arrival
The Hub: Enter the Great Hall (1F). The Grand Staircase is impassable, and the floor is flooded, preventing access to the East Oak Tonc.
The Basement Descent: Move West to the Tidrary (Library) (1F) to find the Basement Key.
The Sump Pump: Enter the Sub-Basement Tunnels and reach the Pomp Room. Flip the Sump Pump Switch to activate the first bit of Hydraulic Logic, which drains the Winch Kitece (Kitchen) Room upstairs.
The Winch Handle: Enter the now-accessible Kitchen to retrieve the Winch Handle.
Phase 2: The Whispering Archives & Attic Search
The Attic Climb: Use the Winch Handle in the Attic Corner to lower the ladder.
Pitch-Black Exploration: In the Servant’s Quarters (Attic), use your Lantern Battery to navigate the darkness and find the Music Box Cylinder.
The Resonance Code: Go to the Tidrary Shety Room (Attic) and drop a Phosphorescent Flare down the "Listening Pipes". This illuminates a 3-digit code on the floor of the Doke Dhonst (Drowned Study) in the basement.
The Clock Puzzle: Proceed to the Grand Lidroary (2F). Use the gear found in The Caretaker’s & Pumphouse to fix the grandfather clock and receive the Minute Hand (Barnacle Key).
Phase 3: The Mechanical Shift & Item Fusion
Tide Clock Activation: Use the Barnacle Key to enter the Boler (Boiler) Room (B1). This starts the Dynamic Flooding timer.
The Tideglass Discovery: Use the Tideglass in the Siren’s Grotto (B1) during "High Tide" to see floating platforms that lead to the Corroded Lever.
Item Fusion:
Find Industrial Grease on the workbench in the Caretaker’s & Pumphouse.
Combine the Corroded Lever and Grease in the Guest Sontes (Safe Room) (1F) to create the Working Mechanism.
The East Wing: Use the Working Mechanism to drain the steam in the East Oak Tonc hallway. Enter the room to place the Sapphire Eye into the taxidermy beast to get the Quill Key.
Phase 4: The Grand Ballroom Finale
Upper Access: Use the Quill Key to open the Private Study and the Grand Ballroom.
The Hydraulic Music Box: Install the Cylinder (from the Attic) and the Burst Gasket (found in the Pumphouse yard).
The Spectral Solution: Activate the music box and use the Tideglass on the Observation Deck to see the spectral sequence of valves that must be turned in the Pomp Room to perfectly harmonize the pipes.
The Ending: As you head toward the Grand Ballroom Skylight for extraction, your Tideglass cracks, merging the past and present for the final boss fight.
