The chests appear in the dungeon after unlocking Gjallarhorn in Collections. Each chest can be looted only by players with the Burdened by Riches debuff. Three Ultra Vandals spawn somewhat close to them, they drop Cursed Engrams when taking damage.
The first chest is located in the large crystal cave after descending into the loot cave, its Vandal stands on a ledge on the opposite wall, across the chasm. The second vandal can be found in the room with containers, after the cistern. The second chest is in the next area after climbing the containers, to the right. The last Vandal is in the Fallen Shield encounter and the chest is at the top of a building under the shield.
The Catalyst's upgrade is unlocked by defeating 400 enemies using Gjallarhorn.
