Every region in Genshin Impact has 10 Shrine of Depths on the land. These buildings are enclosed by a seal of the ancient civilization, waiting for someone to unseal it and unearth the legacy left behind. Typically, players can get Shrine of Depths Keys by leveling up the Statue of the Seven or leveling up the nation's offering system, but there are also other methods, like how in Mondstadt players get Shrine of Depths Keys from quests and the Adventurer Handbook.
