Genshin Impact’s patch 3.4 added more to Sumeru’s desert, including a chessboard puzzle. As you run around the Desert of Hadramaveth, you’ll notice the giant glowing chessboard in Safhe Shatranj. Approaching the blue glowing spots will prompt you to insert chess pieces, which you can find in the new desert area. Collecting and placing all five chess pieces will start the world quest “Apocalypse Lost.”
You should actually find these pieces in treasure chests as you complete “The Dirge of Bilqis” and “The Falcon’s Hunt” world quests. After completing “The Dirge of Bilqis,” the falcon quest line will become available the next real-world day. You will not be able to get all five chess pieces until you do part of “The Falcon’s Hunt.” If “The Dirge of Bilqis” did not unlock upon opening the game after the 3.4 update, you probably still have to complete the prerequisite quest, “Golden Slumber.”
You can skip these chests as you do the quests, but you will see them as you walk through the tombs and caverns the quests take you through, so you might as well stop and grab them.
Once you complete “The Fallen Falcon” (the world quest after “The Falcon’s Hunt) and place the five chess pieces in Safhe Shatranj, “Apocalypse Lost” will start. A sixth chess piece will also spring up in the middle of the board.
After the six chess pieces are up, there are also additional “activation devices” for each piece, found around the map. Each of these devices will float away as you approach them, so just keep following them until you can grab it. There are seven activation devices, and matching them to their respective chess piece will reward a Remarkable Chest for each. Completing all seven will give you the “La Luna Rossa” achievement.
We list out the locations for each of the chess pieces and their activation devices below.
