Destiny 2: How to Open the Mysterious Box | Glimmering Amethyst
In the Mysterious Datapad Riddle and Izanagi’s Burden Sniper guide, we briefly explained how to reach and get the Mysterious Box. In this Destiny 2 guide, our purpose is to be more accurate, telling you exactly what to do to get the Black Armory Key and open the Mysterious Box, once you have collected the previous three keys.
How to Get the Armor Key
When you have collected the Butterfly, Fishhook and Hand keys, you have to go to Ada-1 and ask her for a new task. She will request to collect a Black Armory Key Molt: in this guide, we help you to satisfy her.
First of all, you have to collect 24 Watcher Lenses. To retrieve them go to the Leviathan Raid (in the Nessus destination on the Director). Then you have to open the Underbelly (the code is 1-5-3-3-2-4-6 ) and look for an area plenty of Watchers. We suggest you the Engine Room because you can farm a huge amount of them. All you have to do is kill until you have collected all 24 Watcher Lenses.
The next step requires you to collect 200 Glimmering Amethyst. You can find them in strike chests, public events chests and supply chests or doing Heroics (note that clearing a Heroic Public Event will award you 10 Glimmering Amethyst, while completing a strike like Lake of Shadows will award you 20).
The final step requires you to head to Bergusia Forge and stoke it to Maximum Temper. To do so, you have to kill drones coming into waves. There are basically two spawning points: when you enter the Forge to the right and directly straight from the same starting point. Please note that this is a 650- level activity so it could take some time to clear it.
Taking the Bergusia Forge at Maximum Temper will spawn a chest that drops the so wanted Black Armor Key. You can use it to open the Mysterious Box.
