Genshin Impact: How To Get The Ancient Key For Underwater Door Below The Court of Fontaine

Ancient Key is required to open the door in the underwater area below the Court of Fontaine in Genshin Impact.

It’s quite exhilarating to explore a whole new underwater area filled with lost cities and destroyed ruins in Genshin Impact. While diving in the deep waters south of the Court of Fontaine, players have most likely encountered a locked door that requires an Ancient Key.

Searching for the key is a waste of time since it’s only obtainable while a certain Quest is active in Genshin Impact. The Quest itself is not that hard to complete, but it is time-consuming and Virgil might become annoying later on. The Ancient Key can be obtained early, but it’s highly recommended to just follow the quest to unlock the rest of the Institutes.
