Inside the Mausoleum, the right side of the area, next to the entrance to the Hall of Souls, a myriad of invisible platforms are scattered between solid ground, and two ledges over a vast expanse. Using their Ghost, a Guardian must navigate from platform to platform in order to make it across. The Chest of the Spawn is to the right, and the Chest of the Worm is on the left. Alternatively, the Guardian can run along the ledge on the wall to get to the platform.
