This guide will show you how to find “Orb of the Blue Depths” inside a secret locked room in the game of Genshin Impact 2.6. A Miner’s Key is required to access to locked rooms.
Miner’s Key Location
The Miner’s Key in Genshin Impact can be found while players are traveling around the underground Chasm. Players can find the Miner’s Key in Genshin Impact by investigating abandoned gears in The Serpent’s Cave area.
There are a lot of abandoned gears in the area, so just make sure to check them all. You’ll get either Mora or the Miner’s Key from one of these objects. I have marked the exact location and image of the abandoned gears on the map below.
How To Use The Miner’s Key
The Miner’s Key can be used to unlock the grilled gate west of the Ad-Hoc Main Tunnel Teleport Waypoint. I have marked the location of the gate in the image below.
From the teleport point drop down to the bottom.
Use the Miner’s Key to unlock the gate.
Inside the room, you will encounter a Shadowy Husk enemy named Skeld and a Precious Chest. Defeat Skeld to get one Orb Of The Blue Depth.
