Scent of the Worm is a puzzle found in the Mausoleum aboard the Dreadnaught. At one end of the area, on a balcony overlooking a large abyss, is a locked chest. The chest can only be reached by jumping across a series of invisible platforms, which must be revealed by Ghost scans. Whenever a Guardian steps onto the balcony, Blind Thrall will emerge from the ground and attack them. These enemies are immune to all damage and will continue their harassment so long as the player remains in the area.
