Within the Vow of the Disciple raid, players can spawn a secret chest with great loot. There are a couple of things to note regarding how to get the chest to spawn with something good and where to find it. We'll go over all of that below.
Destiny 2 - How to spawn the secret raid chest
Once per week on each character you have, you can get this chest to spawn with good loot. To unlock the Vow of the Disciple raid, players must complete the first mission of the Witch Queen expansion. When completing the raid, players must get a weapon to drop or the secret chest will only contain Spoils of Conquest.
Destiny 2 - Where to find the secret Vow of the Disciple raid chest
In order to reveal the secret raid chest's location, players must complete the series of Darkness Cruxes. After shooting the last of the cruxes, a room will open to reveal the secret raid chest. Players will have to return to the third Darkness Crux and find the secret room from there. From this area, head forward, jump up the wall, then turn right into the pyramid-like building. The chest will be at the back of this room.
