How to Use Diamond key in Borderlands 3?

how to use redeem diamond keys


To use Diamond keys, head to the Diamond Armory which is a room under the bridge on Sanctuary III’s upper deck. It’s a room that is packed with awesome loot as well as the Diamond chest. You need to activate the Diamond chest with your one-time-use Diamond key and then the room will transform unveiling a lot of new items to loot.

Do note that once you open up the Diamond chest, a timer will get activated. Make sure you check out all the available gear before time runs out. That’s because you are only allowed to take one piece of loot from every wall in the room. After the timer runs out, the shutters will close and if you missed, well, you won’t miss much. You will still get a random item from a wall that you missed, which you may or may not want. But still, it’s good that you won’t go empty-handed.

That’s not all. You will also get Legendary gear from the room after the shutters close.
