Powering the Diving Equipment
Your journey into the deeper cave systems begins with powering the diving equipment. This initial step is relatively straightforward but essential. You'll need to locate a green power box and activate specific switches to get the machinery running.
Locate the Power Box
From the main diving suit area, look for a yellow wire leading away from the machinery. Follow this wire to its source, which is a green power box mounted on a wall.
Identify the Switches
The green power box will have several numbered switches. Your goal is to flip the correct ones to bring the power gauge into the green zone.
Activate the Switches
Flip switches 2, 3, and 5. This combination will correctly power the diving equipment, indicated by the gauge moving into the green section.
Fill the Oxygen Cylinder
Once power is restored, place the empty cylinder (found nearby) into the machine's holder. Turn on the small power panel, rotate the wheel into the green zone, and press the yellow button to fill the cylinder. Attach the filled cylinder to the diving suit.
Successfully powering the diving equipment is your first major step in solving the Call of the Elder Gods cave puzzle. It unlocks access to the underwater chambers and subsequent challenges.
Black Ooze Separation Puzzle
Once you're underwater, you'll encounter a peculiar machine designed to separate black ooze from water. This is a classic liquid-transfer puzzle that requires careful management of the tanks. The goal is to isolate four units of black ooze in the second tank.
Objective
Isolate four units of black ooze in the second tank.
Mechanism
A machine with multiple tanks and transfer valves for water and ooze.
Follow these steps to successfully separate the black ooze:
Initial Transfer
Fill the first tank completely. Then, transfer its contents to the second tank. Next, direct only the water from the second tank into the small, third tank.
First Ooze Accumulation
Repeat the fill-and-drain process until two black ooze units remain in the second tank. This sets up the base for further accumulation.
Second Ooze Accumulation
Fill the first tank again. Carefully manage the flow direction to ensure the second tank reaches three black ooze units with no water. This might require transferring water out again if you overfill.
Final Ooze Isolation
Fill the first tank one more time. Transfer its contents to the second tank until it holds precisely four black ooze units.
Send Ooze Upward
Once the second tank contains four units of black ooze, press the vertical-pipe button to send the ooze upward, completing this phase of the Call of the Elder Gods cave puzzle.
This puzzle requires exact measurements. If you make a mistake, you might need to reset the machine or carefully reverse some steps. Patience is crucial here.
Tower Piano-Like Control Panel
After successfully handling the black ooze, you'll need to manipulate ancient towers using a control panel that resembles a piano. Harry's journal will contain crucial mural notations that guide these sequences.
Key Tower Sequences:
- Raise Towers: 1-2-4-5 + C
- Rotate Towers: 1-1-4-4 + C
- Reset Towers: 4-4-1-1 + C
- Raise Higher: 1-2-4-5 + C (again)
- Clean Sequence: 1-4-2-3 + C
- Fire Sequence: 4-2-5-3 + C
The "C" in the sequences refers to a specific activation button on the panel, often marked or distinct from the numbered keys.
Here’s how to navigate the tower controls:
| Sequence Name | Input (Keys + C) | Purpose | Notes |
|---|---|---|---|
| Raise Towers | 1-2-4-5 + C | Lifts the towers from their initial position. | First step to access the tower interiors. |
| Rotate Towers | 1-1-4-4 + C | Rotates the towers to reveal a left-tower doorway. | Allows entry into the left tower. |
| Reset Towers | 4-4-1-1 + C | Rotates the towers back to their original state. | Useful after inspecting the left mural. |
| Raise Higher | 1-2-4-5 + C | Elevates the towers further after initial raise. | Necessary for the statuette process. |
| Clean Statuette | 1-4-2-3 + C | Applies a "clean" process to the statuette. | Part of the ritual preparation. |
| Fire Statuette | 4-2-5-3 + C | Applies a "fire" process to the statuette. | Completes the statuette preparation. |
| Freeze Statuette | 3-5-2-4 + C | Activates an alternate "freeze" sequence. | Unlocks the "Best Served Cold" achievement. |
After successfully inputting the "Clean" and "Fire" sequences, you can send the statuette down through the dumbwaiter. This concludes Harry's segment of the Call of the Elder Gods cave puzzle, allowing you to continue as Evangeline.
