Chest PuzzleEdit

Inside the Lighthouse, there is a gate with a chest behind it. To open the gate and access the chest, a Guardian must activate glowing symbols in the following order:[1]

  1. On the table near Brother Vance.
  2. On a bookshelf on the right-side wall.
  3. In a stack of books near a bookshelf on the left-side wall.
  4. On a table on the right side of the room.
  5. High up on a shelf near the Forge.
  6. On a conflux that spawns on the right side.

After activating the conflux, a waypoint will appear that leads to the loot chest under the bridge.

Taking too long between symbol activations will cause progress to be reset.
