Genshin Impact the Miner’s Key and Gate Location spot to the Black Serpents.
In Genshin Impact, the Miner’s Key is a special item that can be used to unlock locked doors in the game’s mines. These locked doors can be found in various mine locations throughout the game, and accessing them requires the Miner’s Key.
The Miner’s Key can be obtained by completing the quest “A Mysterious Loss” which is given by the Adventure Guild in Mondstadt. The quest is available after reaching Adventure Rank 20 and it’s a simple quest chain that will lead you to the key.
Once you have the Miner’s Key, you can use it to unlock the locked doors in the mines, allowing you to access new areas and collect valuable resources such as Ore and Crystal Chunks.
