Updated August 24, 2026 · Checked for the current launch build
Quick answer: Bring the Crypt Key and a working sidearm. Break the false wall, drop into the hole, use the hidden return passage, stand on the pressure plate and shoot the bell. The bell repairs the gap; cross it and strike the pillar onto the plate to hold the final door open.

Before enteringCrypt Key from Desolate Peak, above Illusionist's Cache
Complete route
- Collect the Crypt Key at Desolate Peak, in the structure above the Illusionist's Cache dungeon. Check the table or shelf near the rear entrance.
- Travel to northeast Fainweald. The locked crypt door is north of Grisha Hunting Grounds and south of Stones of Remembrance.
- Unlock the door, take the elevator down, descend the stairs, and clear the coffin enemies hiding in the entrance tunnel.
- At the bright wall blocking the tunnel, attack the surface. It is a false wall and opens the route to the puzzle chamber.
- Drop into the hole beside the pressure plate, defeat the two ghosts, collect the Laterite from the white branch, then attack the wall at the top of the stairs to reveal the return passage.
- Back at the plate, stand on it and aim a sidearm through the raised opening. Shoot the large bell; hit the nearby Resolve stalk first if you cannot fire.
- Cross the repaired floor, move behind the stone pillar, and strike it toward the pressure plate. Center it until the final wall stays raised.
- Inside the reward room, check the sheep for the reported optional Totem, inspect the bone chair, and open the chest before touching the white exit light.
