How to Solve the Mirror Puzzle in Assassin’s Creed Odyssey

As you progress through the main storyline in Assassin’s Creed Odyssey, you’ll reach the Volcanic Island of Thera, where you’ll search for clues about your real father. One clue triggers the objective to “open the door,” which involves moving several mirrors to direct sunlight onto a mirror above the doorway. Here’s how to solve the mirror puzzle in Assassin’s Creed Odyssey:

Where to Start the Mirror Puzzle in Assassin’s Creed Odyssey

Start the mirror puzzle in Assassin’s Creed Odyssey by traveling to the Volcanic Island of Thera. As you search for clues about your real father, the puzzle will trigger as part of the main storyline. First, loot a chest in your father’s camp to find a tablet. The tablet reveals your father’s discovery of a door and several mirrors that must be adjusted to unlock it.

After reading the tablet, you’ll need to open the door by manipulating the mirrors around the island to direct light onto a mirror above the doorway. This marks the start of the puzzle.

Mirror #1: Obstructed

Head south from the dock on the Caldera of Fate. You’ll find several mirrors reflecting light, but one mirror is obstructed by wood. Destroy the wood to continue the light path.

Mirror #2: Blocked Doorway + Covered Scaffolding

Follow the light into the nearby building. The beam dies out at a blocked doorway, so destroy the boards to let it pass. Inside, you’ll find scaffolding covered with a sheet that blocks the light. Move the scaffolding to let the light reach the second mirror.

Mirror #3: Move Neighboring Mirror

Next to mirror #2 is another moveable mirror. Push it as far away as possible, clearing the path for the light to reach mirror #4.

Mirror #4: Catch the Light from Mirror #2

Now that mirror #3 is out of the way, adjust mirror #4 to catch the light from mirror #2. This will redirect the beam out of the building and toward the dock area.

Mirror #5: Clear the Obstructions

On the top floor of the building near the dock, there’s a fixed mirror that’s obstructed by items. Clear these items to allow the light to reach the floor below, where the final mirror awaits.

What’s Behind the Door?

In the room below, eliminate the snakes around the final mirror. Look south to find a doorway blocked with boards. Destroy the boards, and the light will shine onto the door, opening it.

What’s Behind the Door?

After opening the door, a cutscene will trigger, and you’ll enter a mysterious area. This leads to Atlantis and your father, starting the Gates of Atlantis mission. Here, you’ll encounter Pythagoras and unlock more lore about the Lost City.
