Anniversary St. Francis Folly: Four Keys and the Central Shaft

Four chambers, one objective

St. Francis Folly revolves around four keys: Hephaestus, Poseidon, Atlas and Damocles. The central vertical room connects their trial areas. Treat it as your navigation hub and note which chamber you have already completed.

Keep the trials separate

Each named room uses its own hazards and mechanism. A solution from the water chamber does not open the sword-trap chamber. Work through one route, obtain its key and return to the shaft before switching objectives.

Watch the direction of travel on the way back. A ledge that was a safe drop on entry may require climbing on the return trip. Use the camera to identify the next handhold before committing to a long jump.

At the exit

Bring the collected keys to their corresponding locks. If a lock remains unusable, check the key inventory and the unfinished chamber rather than repeating a solved puzzle.

For an illustrated room-by-room explanation, use the linked reference. The route diagram here is an objective checklist, not a scale map of the shaft.
