Destiny 2 Curse of Osiris Eater of Worlds Secret Chest Location
If you are planning to make another trip to the Raid Lair, then you should probably read on to find out where the chest is hidden and how you can acquire it for yourself.
The Secret Chest has recently been discovered online and it should not be a problem for you to find it once you are aware of its existence. Now we will tell you where the chest is located.
The chest can be found right before you enter the arena of the boss fight. You will be tossed out to an open area which will have tons of debris flying around all over the place.
You have to reach the platform below safely to advance.
Before you do that though, there are six rings that you can fly through as you are making your way down. You need to activate all of the six rings if you want to get the secret chest.
It should not be that hard since you will have your team with you and all of you will have the chance to get the rings. Just remember that if you fail, all of you will have to start over.
The best way to do this is to kill your characters.
One last thing to remember is that if you move too far then you will trigger the next event of the raid lair. If this happens and you have failed to acquire the rings by this time, then you will have to restart the entire raid lair to get your hands on the chest.
