Light Citadel/Act‑2 spoilers. This guide covers the route to Cogwork Core’s top chamber and a consistent method to solve the four‑pillar music puzzle to earn Architect’s Melody.
Overview
Architect’s Melody is learned at the top of the Cogwork Core after solving a four‑pillar rotation puzzle. You’ll typically approach from Choral Chambers, climbing through cog/ring segments and benches to the final chamber with spotlights.
TL;DR
- Where: Cogwork Core, topmost room.
- Goal: Rotate each pillar’s segments so the yellow connector lines form a single top‑to‑bottom path; when correct, a pillar sinks. When all four lower, play Needolin in the center to learn Architect’s Melody.
- Why: One of the Threefold melodies used for main progression around the Citadel/Conductors.
- Video: Full route and solution in the embed above.
Requirements & Prep
- Movement: Clawline/Grapple recommended for vertical rings and hooks.
- Safety: Grab benches along the climb; bring silk for binds between hazards.
- Optional: Talking to the Twelfth Architect during Core progression helps context and routing.
Route to the Puzzle (Fast Path)
- From Choral Chambers central sections, drop into the Cogwork Core entrance shaft.
- Ascend through cog/ring rooms, using Clawline for hooks and careful wall‑work; take benches as needed.
- Enter the top chamber with four tall pillars and swiveling spotlights—the puzzle room.
Puzzle Mechanics
- Four pillars, each with four stacked, rotatable segments.
- Strike the pillar plates/levers to rotate segments.
- Align the yellow connector lines so each pillar has one continuous path from top to bottom; a solved pillar sinks.
- It’s dark: hit spotlights to swivel and illuminate segments.
- Rightmost pillar can be awkward—use wall‑jumps/hops to tag plates safely.
Reliable Solve Method
- Illuminate first: swivel spotlights to see connectors clearly.
- Work one pillar at a time, starting left → right.
- Match connectors in order:
- Bottom‑up: align the lowest segment to match the one above; repeat upward until it sinks.
- Or top‑down: set a clean top and match downward—both methods work as long as the line is continuous.
- Repeat for all pillars; when all lower, play Needolin in the center to receive the Melody.
Reward & Next Steps
- Unlocks: Architect’s Melody (part of the Threefold set used at Conductor statues in Citadel/Chambers).
- Progression: Advances Act‑2 routes through Citadel interiors and linked areas.
Troubleshooting
- Pillar won’t sink: a connector misaligns between two segments; rotate again until the path is unbroken.
- Lighting issues: re‑aim spotlights—misreads happen in the dark.
- Plate reach: wall‑jump on the rightmost pillar to strike plates easily.
