In recent scenarios, you might have come across some spheres that are named Orb of the Blue Depths and are not sure how to use it. These are collectibles that are used to open a certain secret door in the world of Genshin Impact.
In this guide, we’ll show you where and how you can use these orbs.
How To Use Orb Of The Blue Depths
Before you can use the Orb of the Blue Depths, you must need to collect 9 of them to be able to open the secret door. It shouldn’t be as hard to collect as they are mostly scattered across the map, behind enemies or gated puzzles.
Once you get the orbs, head onto the upper levels of the upside-down city. The Secret Room is found in the area through the large tree root on your way to the central ruin.
NOTE: The area inside can only be accessed after you’re done with the archon quest.
Once you are done with those, head to the inverted waypoint and start the journey there.
First you need to climb the wall in front of you, head straight afterwards until you see a wall. From there, head left and you should see a mechanism that looks like a sphere on the floor.
Interact with it to trigger selection of your orb and you’ll be rewarded with a letter and three chests of loot!
