Family’s Legacy is one of the main story quests in Assassin’s Creed Odyssey. It’s the one where you have to enter a cave on the Volcanic Islands, but the massive stone door is locked. In order to unlock and open the door, you’ll have to complete a mirror puzzle, in which you redirect light to open the lock. Some people don’t like it one bit, and if you’re one of them, our AC Odyssey Family’s Legacy quest guide will show you how to solve it quickly.
How to solve mirror puzzle and open door?
Once you arrive at the island, go to the door. On the plateau above it, you’ll notice a ray of sunshine being reflected off of several mirrors. Go to where the ray ends, and you’ll see a mirror blocked by some boards. Destroy the boards, and the beam will be on its merry way. Follow it, and you’ll find a boarded-up window blocking it. Break the boards and let the light flow once more.
Follow the ray again, and you’ll end up across the road, in another ruined building. Move the shelf with the sheet to let the sun reach the mirror, then move the other two shelves as well – if you move the one with the mirror all the way to the door, it’ll reflect the beam into yet another building.
Once you get there, you’ll have to move the shelves so that the ray goes down through the hole in the floor and into the dark room. Follow it down there, and break the boards blocking the door. This will allow the ray of sunshine to reach the door, and you’ll finally be able to enter the cave and continue your quest for the truth, glory and justice.
