Mona’s domain in Genshin Impact’s “Summertime Odyssey” event is a doozy, simply because after running it once for the story, you need to head back in to explore passages that open after. There is one Echoing Conch and 15 chests in there, so you’ll want to scope it out to get all that sweet limited-time loot.
Our “Temple of the Star Latitudes” event walkthrough will explain how to solve the astral puzzles, seize destiny, and complete “The Ancient Azure Stars” domain.
The Ancient Azure Stars story domain walkthrough
Once you jump into the pool, you’ll end up in the central chamber of Mona’s domain. Pick up the two marked Asterism Shards on the ground and place them in the left mechanism so that they match the symbol on the door.
Next, you’ll have to “solve the astral puzzle,” but hitting and aiming the Star Guides on the floor to match the pattern on the ceiling. You can solve the puzzle by setting up the Star Guides like this:
Collect the Asterism Shard from the chest and follow the star-shaped Seelie out of the room and into the pool. Follow the star through the maze as Mona and complete the bullet hell star-dodging segment for a cutscene to play.
Back in the Golden Apple Archipelago, head to the marked location, defeat the Hilichurl, and interact with the spot it was digging to grab another Asterism Shard. Place your two new shards into the mechanism on the right to open the door.
In the next room with Star Guides, interact with the star on the pillar towards the left to bring up another star Seelie to show you where the answer to the puzzle is. If you’re having a hard time seeing it, just arrange the Star Guides like this to “solve the astral puzzle” again:
Pick up the fifth Asterism Shard and head back to the central chamber and jump in the pool.
Head through the “mirage maze” by using the stars above as a guide. Just keep running Mona in straight directions until she hits a wall until you head north to reunite with the star Seelie again.
Back in the Golden Apple Archipelago, again follow the quest navigation, defeat the Hilichurl and check out the spot it was digging in for another Asterism Shard. Go back into Mona’s domain and investigate another Asterism Shard by the left mechanism. (You will need this later for exploration!) Place the two corresponding shards into the north mechanism and head through the door for another Star Guide puzzle.
The solution to the puzzle is through a door on the right, but if you don’t want to think too hard about it, just set up the Star Guides like this:
Again, grab the Asterism Shard from the chest and head back to the central chamber. Rather than jumping in the pool, remove the bottom shard from the mechanism that points northeast and use that as the top part for the fourth chamber.
Head in and activate the mechanism in the middle to show a pineapple-like shape. Make the shape with the Star Guides like how we did below:
Open the chest, pick up the Asterism Shard, and follow the star Seelie. After following the path, a cutscene will play, and eventually you’ll be playing as Mona again.
To “follow the star to the destination” just keep running down the halls. Similarly to when Mona actually had a star to follow in the beginning of the domain, the walls will move on their own to reveal a path as you approach them. Eventually, you’ll loop around and find a star. Follow it to get to the last portion of the domain.
To “seize destiny” as Mona, you’ll need to catch the moving star that’s floating around the others. Once you do, an illustrated cutscene will play and the story portion of the domain will end.
After finishing, you can interact with the platform to head back into Mona’s domain, where more rooms will unlock, allowing you to get more treasure chests and an Echoing Conch.
The Ancient Azure Stars domain chests and conch locations
There’s a lot in here, so we’ll break it up by which gate you have to enter.
North temple entrance
The door that had the constellation floating in the water is now open, so head through there.
Following the path, there’s yet another Star Guide puzzle. Hit this rock in the back to reveal the full constellation on the wall.
Set up the Star Guides like so:
Grab the chest and head straight towards the back wall, which will reveal a hidden passage.
The room with the Exquisite Chest has yet another rain rock in it (like the one you hit in the previous room to reveal the full constellation). Break it to show the true location of the Exquisite Chest in the center.
Head up the stairs towards the back to reveal yet another hidden passage.
In here, there’s an elemental pillar puzzle. While they all look like Hydro pillars, checking the reflections on the ground will reveal that three of them are actually Anemo and Pyro pillars. Use the Door of Resurrection to swap out your party members if you need to, hit the pillars with their corresponding elements, and grab the chest.
There’s another hidden doorway in the back of this room, so head through it. Break the rock on the left side and light these torches to grab a Common Chest.
If the torches on the right side are lit, use a Hydro character to put them out. Run back to the first room with the pool of water, and you’ll notice the water is drained. Grab the Common Chest at the bottom.
South temple entrance
Head through the entrance to the area and go up the stairs on the sides and into the now-open door in the back. Keep following the path until you get to a Star Guide puzzle, which will change as you solve it.
Set the Star Guides like so:
An arrow will now appear, but it’s not for the Star Guides. Instead, that arrow is leading to a secret door hidden at the wall it’s pointing towards. Head up the path and you’ll see the last Echoing Conch in the room on the left.
The puzzle in this room requires you to shift the stars around so the constellation in the sky matches the one on the floor. To do this hit the right button twice, the up button three times, the down button once, and the left button twice.
Once you do this, grab the unlocked chest and follow the star Seelie that appears from the constellation in the sky. Follow it down the chasm and complete the “Challenge of the Starry Sky.” Head through the door once you complete it and grab the newly spawned Luxurious Chest from the central chamber.
Southwest temple entrance
After entering the main room here, head up the huge spiral staircase to enter a newly-opened area. A star Seelie will lead you up, thought you can’t follow it. You will need to create a path for yourself using the Star Guides. Set them like so:
Head up the starry path you made, touch the star, and open the chest. Take the newly created elevator up and grab the Common Chest sitting on the ledge. Swim back to the elevator and take it up again to grab another Common Chest. Take the elevator back all the way down.
Head back to the room with the spiral staircase and use the mechanism at the bottom to make another elevator appear. Take it up to grab a third Common Chest.
Northeast temple entrance
Head through this entrance and continue to the back of the room, where there’s a new path to take. This will put you in a room with more Star Guides, as well as cube mechanisms. Activating the mechanisms will make the Star Guide constellation appear on a wall, but if you don’t want to deal with all that, just set up the guides like this:
Grab the chest and continue forward. At the next room, which has a starry bridge, go left of the initial platform and interact with the star on the ledge.
Walk across the starry path and jump down on the ledge to collect another star.
After grabbing it, just walk across the seemingly-nothingness to get back to the start. Don’t worry; you can’t fall. Head to the back of the room to touch the last star, near the Asterism Shard mechanism. Put the extra Asterism Shard you found while doing Mona’s story domain into the mechanism. Arrange the Star Guides like this:
Central temple entrance
Head down the steps into the imaginary Mondstadt and touch the globe. There’s another puzzle with the four buttons, so hit the buttons in this order: down, right, up, left. A door will appear after successfully making the stars look like this:
Enter the door and you’ll be back in the central room with another Luxurious Chest.
That’s it for Mona’s domain. You can interact with her event portal to make sure you’re not missing any chests.
