Mortal Shell 2 Chapel Key

The Chapel Key is a location-specific key, so keep it for the matching chapel door rather than testing unrelated crypt or Blackmarrow locks. The current community reference catalogues it as a key item. ^[wiki]

If a door does not prompt for it, mark the location and continue exploring; key names are deliberate. Because community pages are still being updated after launch, verify the route against your current patch before treating a screenshot as exact.
