Chest of Yuul

The Chest of Yuul is an obtainable loot chest on the Dreadnaught. It is located at the Hall of Souls, across the right side of the Court of Oryx. It requires the Key of Yuul, and can contain Hadium Flakes, Decoherent or Legendary Engrams, or a Calcified Fragment.

Location
The chest is located on a high ledge, on the opposite side of the entrance to the Hull Breach. Only two very small transparent platforms are available for the Guardian to jump on, making it a very difficult leap of faith.
