Note that you must have the star beside you at all times as you'll need it to transport itself to the center.

8. Dive in the water

After the Star goes down the pool in the middle of the room, jump in the water to transport yourself to another dimension!

9. Follow the star to the destination

As Mona, explore the new space and follow the star. This step is fairly linear, so don't lose sight of the star as it will guide you to the right direction!

10. Beat the Challenge of the Starry Sky

Avoid the shooting stars to complete the Challenge of the Starry Sky in under one minute. The hit limit you can take is only 30, so try to avoid the bullet hell at all costs!

The room beyond will be another puzzle for treasure chests. For the sake of completing the quest, we'll go back to the main room for now!

Follow the star that appears from the Exquisite Chest and dive back in the main room with it!

Note that the star must also go inside the pool to be able to enter the dimension!

8. Find the destination of the Mirage Maze

The star on the map in the sky will guide your current position. Reach the exit to find the destination of the Mirage Maze.

The walls are invisible, but you can bump on it to get a better feel of your surroundings. Imagine the shape of the walls in your mind and match it with the maze map for you to visualize where you are!

9. Find the Mirage Door exit

Head up the translucent stairs and go inside the mirage door to go outside of the domain!

This will complete Part 2 of the quest!

If successful, the Exquisite Chest will appear with the eighth Asterism Shard and another Strange Star inside!

6. Follow the third Strange Star

Return to the Main Room with the star once more, but it won't actually move to the pool. This time, you have to solve the last room of the domain to get the other pair!

In one of the sections, the star will backtrack, and you have to go back and approach the wall where it phased through. This will reveal another hidden path.

14. Turn Left on the Forked Path

When the walls change and three paths emerge, simply go left. The star will also move on that direction too!

15. Jump towards the hole

Once you see a big chasm, jump down and walk forward. Don't worry about falling as an invisible bridge will let you stay afloat!

Afterwards, keep heading forward until you see another hole, then jump once more.
