The 3.4 update for Genshin Impact added another fishing point in Sumeru's deserted area. The new area introduced many new fish and nine fishing spots, but the most recent Desert of Hadramaveth expansion had the tenth hidden under the sands.
Three fishing areas in Sumeru's Desert areas, including the hidden one, are currently available. Two are located in the Land of Lower Setekh and one in the Desert of Hadramaveth, behind Mt. Damavand. Despite the small amount of water there, players in the deserted area of Sumeru have fewer fishing spots.
Players will encounter an underground river that flows past ancient desert walls and green areas, which forms a small pond large enough to hold some of the most famous Sumeru fish.
Sandstorm Anglers, True Fruit Anglers, Halcyon Jade Axe Marlins, and Lazurite Axe Marlins might be found if players go there at night.
Players will have to first teleport to the underground teleport in the area to get to the hidden fishing spot. They will only need to complete the main quest in The Dirge of Bilqis to unlock it.
Players will find a river below them when they reach the underground caves. They will then have to follow the river's current all the way to the left before reaching the pond where the fishing spot is located.
Due to the presence of several monsters near the fishing area, players will need to clear the small grass area to where they can fish before putting the hook in the water.
