This guide shows where to find Day 5 Phantasmal Conches in the game Genshin Impact 2.8. The last Phantasmal Conch is located inside Mona’s domain – ‘Temple of the Star Latitudes‘. You can pick it up while in the ‘Ancient Azure Stars’ event quest, or by revisiting the domain later.
Day 5 Phantasmal Conch Location
The Phantasmal Conch inside Mona’s domain is located behind the first door you entered during the story.
In case visiting the first time: Enter the first door and solve the Astral puzzle to summon the chest in order to open the door up the stairs to the back of the room to gain access to the next area.
Go up the stairs and enter the room on the rear to reach a new area if you have already solved the Astral puzzle and obtained the chest.
Proceed ahead until you reach an area with translucent bridges. Cross the translucent bridges to reach the next area. In the new area, you will have to solve another Astral puzzle. Input the three correct patterns that appear on the wall in order for the wall constellation to change to an arrow pattern.
Puzzle 1
Puzzle 2
Puzzle 3
On solving the three puzzles, stars will form an arrow. Go to the wall the arrow is pointing at and touch it to reveal the next area.
Enter inside, then take the astral path up to a room with four circular switches on the floor. On the left side of these switches is where you’ll find the Phantasmal conch.
