Cogwork Core mixes sawblade platforming with clever shortcuts; clear lower routes, then climb to solve the pillar puzzle.
Unlock the area map, grab the Mask Shard and Spool Fragment, open the central gate, then learn the Architect's Melody and exit to Whispering Vaults.
1. Obtain the Cogwork Core Map.
From Choral Chambers, re‑enter the Dancers arena and drop through either hole.
Enter the white‑lit building, spin the ceiling wheel to spawn a Bench, then step on the plate above to unlock the Cogwork Core map.
2. Complete the west gauntlet for a Mask Shard.
Drop carefully—float to avoid saws; head left to the arena beyond two Cogwork Spines.
Clear waves as floors shift; exit left to a Mask Shard and press the shortcut plate back to west Choral Chambers.
3. Obtain the Spool Fragment to the southeast.
Return and descend; slip past Choirbugs and a Cleanser, then take the lower‑right exit.
Spin the top‑right wheel to open the gate and spawn a Clapper miniboss; proceed through vents to claim the Spool Fragment, then use the lever shortcut out.
4. Unlock the central gate.
Back in the shaft, cross saw runs; pogo the last saw to reach a wheel above.
Spin it to open the central gate, easing travel between left and right halves.
5. Reach the top of the Cogwork Core.
Climb into the upper section above the Dancers; drop a Clawline hook into their arena for future access.
Solve the moving‑hook track puzzle, defeat a Defender/Cleanser, open the gate, and exit through the top‑left ceiling.
6. Solve the puzzle to learn the Architect's Melody.
At the summit, align all four segmented pillars via nearby levers until each descends.
Stand on the plate, play the Needolin when prompted, and learn the Architect's Melody.
7. Reach the Whispering Vaults.
Return to the lower right path; unlock the door and rejoin the Choral wheel room from the left.
Push the block, clear the arena (Vaultkeeper finale), then exit right into the Whispering Vaults.
