- Main Objective: Use the five-key music panel to manipulate stone towers and refine ancient statuettes.
- Raising Towers: Input the sequence 1, 2, 4, 5 followed by the confirmation button to elevate structures.
- Rotation Logic: Use 1, 1, 4, 4 for counter-clockwise and 4, 4, 1, 1 for clockwise movement.
- Refinery Phase: Fill the statuette with water and black ooze using specific shelf-based dot notations.
- Endgame Puzzle: Align the four spheres in Pnakotus by timing their movement based on 80 and 90-degree offsets.
The Chapter 2 Tower Control Panel
In Chapter 2 of Call of the Elder Gods, players encounter a massive subterranean chamber containing ancient stone towers. To progress, you must master the music-based control panel located on the stone ramp. This panel features five distinct keys that emit specific tones. Before you can operate them, you must progress the narrative until the keys glow with a light green hue, indicating they are powered and ready for interaction.
Video Highlights:
- Detailed walkthrough of the Chapter 2 music puzzle mechanics.
- Visual demonstration of the tower raising and rotation sequences.
- Explanation of how to interpret the mural clues for the refinery process.
- Step-by-step guide to creating the necessary statuette.
The tower puzzle requires three primary types of manipulation: raising the height, rotating counter-clockwise to reach specific entrances, and rotating clockwise to access different murals. The following table provides the exact inputs required for each action on the five-key panel.
| Action Type | Key Input Sequence | Confirmation Required |
|---|---|---|
| Raise Towers | 1, 2, 4, 5 | Yes |
| Rotate Counter-Clockwise | 1, 1, 4, 4 | Yes |
| Rotate Clockwise | 4, 4, 1, 1 | Yes |
| Lower Towers | 5, 4, 2, 1 (Reverse) | Yes |
The keys are numbered 1 through 5 from left to right. Always remember to press the circular confirmation button after entering a sequence, or the towers will not move.
The Statuette Refinery Process
Once the towers are raised and accessible, the call of the elder gods tower puzzle shifts focus toward the refinery. You will find a statuette in the leftmost tower that must be placed in a contraption within the right-hand tower. This process involves two critical stages: filling the statuette with water and then with black ooze. The solutions are hidden within murals that use a shelf-like notation system.
Retrieve the Statuette
Rotate the towers counter-clockwise (1, 1, 4, 4) to align the entrance of the leftmost tower. Enter and pick up the statuette from the floor.
Placement and Preparation
Rotate the towers clockwise (4, 4, 1, 1) to access the right tower. Place the statuette on the pedestal near the water-filling station.
Water and Ooze Separation
Interact with the control panel to separate the liquids. You must interpret the dots on the murals as shelf positions to determine which keys to press.
The refinery puzzles are often considered the most difficult part of Chapter 2. The notation system requires you to look at dots positioned on five horizontal "shelves" and translate them into key presses (1-5).
| Liquid Type | Mural Shelf Sequence (Bottom to Top) | Final Key Code |
|---|---|---|
| Black Ooze | Shelf 1, Shelf 4, Shelf 2, Shelf 3 | 1, 4, 2, 3 |
| Purified Water | Shelf 4, Shelf 2, Shelf 5, Shelf 3 | 4, 2, 5, 3 |
| Statuette Activation | Shelf 1, Shelf 2, Shelf 4, Shelf 5 | 1, 2, 4, 5 |
Successful completion is signaled by a purple hue emitting from the statuette. Once this occurs, place the item in the dumbwaiter to send it to Evangeline.
Ancient Statues and Cryptographic Codes
As the journey continues into Chapter 3 and 4, the puzzles evolve from mechanical tower manipulation to complex logic and cryptography. In the Starry Wisdom Society's chamber, you must identify the roles and symbols of five cult members. This requires cross-referencing notes found in individual offices with a developed photograph.
| Member Name | Professional Role | Code Name | Hieroglyph Symbol | Mask Type |
|---|---|---|---|---|
| Howard | Dilettante | Orion | Crocodile | Crocodile |
| Patricia | Biologist | Corvus | Pot/Semicircles | Cat |
| Felix | Archaeologist | Auriga | Snake | Long Beak |
| Eugene | Psychiatrist | Eridanus | Little Bird | Dog |
| Larry | Astronomer | Lynx | Eagle | Eagle |
In Chapter 4, the "tower" takes the form of a radio station. To gain access to the reinforced door, you must use an Enigma machine to decrypt three specific messages. The codes are based on the date of the communication and the general currently in command.
| Message ID | Date (2026) | Disc Setting | Dial Setting | Plug Pairs |
|---|---|---|---|---|
| UZW | Feb 25 | II, III, I | 23, 13, 2 | GE, FM |
| BDA | Jan 01 | III, II, I | 19, 25, 6 | PW, CR |
| SSW | Jan 03 | I, III, II | 15, 25, 25 | ZI, HP |
The code for the reinforced door is 9519. This is derived from General Hohenberg's ID (95) and the last change date (19th of February).
The Pnakotus Gate and Sphere Alignment
The climax of the call of the elder gods tower puzzle occurs in Chapter 6 at the desert entrance of Pnakotus. This puzzle uses a circular platform with four spheres that must be set in motion with precise timing to generate specific light patterns. You must use mirrors to redirect light rays to activate the mechanisms before the spheres can be manipulated.
Pattern 1: The Wave
- Set the second sphere in motion first.
- Wait until it travels roughly 80 degrees.
- Launch the first sphere to create the 'S' shape.
Pattern 2: The ISS
- Set the fourth sphere in motion.
- Wait for a 90-degree gap.
- Launch the second sphere to match the mural.
Pattern 3: The Final Gate
- Launch the third and fourth spheres simultaneously.
- They must move in perfect synchronization.
- Manipulate all three switches to open the door.
The timing for these spheres is unforgiving. If you miss the window, you must stop all spheres and reset the puzzle to avoid desynchronization.
| Pattern Step | Primary Sphere | Delay Angle | Target Symbol Shape |
|---|---|---|---|
| First | Sphere 2 | 80 Degrees | Wave with Dot |
| Second | Sphere 4 | 90 Degrees | Triple Wave (ISS) |
| Third | Sphere 3 & 4 | 0 Degrees | Large Gate Crest |
Before attempting the sphere timing, ensure the light beam from the cliff mirrors is hitting the circular structure on the wall. Without this light source, the spheres will not generate the required patterns.

Essential Puzzle Milestones:
- Raise the Chapter 2 stone towers using the 1-2-4-5 sequence.
- Refine the statuette by separating the black ooze (1-4-2-3).
- Correctly assign the five masks to the Egyptian statues in Chapter 3.
- Decrypt all three Enigma messages in the radio tower.
- Unlock the Pnakotus gate by timing the sphere rotations.
- Solve the mind-swapping wire puzzle in the final facility.
FAQ
Q: How do I know which key is which on the music panel?
The keys are arranged horizontally from left to right. The leftmost key is 1, and the rightmost key is 5. The circular button below or to the side is the confirmation trigger.
Q: Why won't the towers move even when I enter the correct code?
You must first standing on the glowing circular pressure plates nearby to power the machinery. Additionally, ensure the keys are glowing green; if they are dark, you haven't triggered the necessary narrative dialogue yet.
Q: What is the solution for the mind-swapping machine in Chapter 5?
This puzzle involves connecting colored wires. A green light indicates a wire is in the correct spot, while yellow indicates it is in the right section but wrong terminal. Use trial and error based on these light cues to find the unique configuration.
Q: Is there a way to reset the Pnakotus sphere puzzle?
Yes, you can manually stop each sphere by interacting with its specific control lever. It is highly recommended to stop all spheres and wait for them to return to their starting positions before attempting a new pattern.
