Whenever you find a looking glass, interact with it to enter the other side. Here, you will find yourself in a room with a painting of sunflowers and a small glowing fish. In each looking glass location, there’s something you must do to make the fish swim through the painting. Once that is done, the looking glass location is ‘completed’.

The overview below will show you all “Through the Looking Glass” hidden mirror locations in more detail, and explain each painting puzzle.

After going through the looking glass, light up the torches below the flower painting, using Pyro attacks, and turn off the other four torches using Hydro attacks. This will make the fish swim through the painting.

The path to the treasure chest is obstructed by invisible walls, but if you swim low and stick to the right, you’ll be able to reach it. Open the chest to release the fish.

Once you’ve completed the six looking glass puzzles, you’ll be transported to the world inside the “Book of Esoteric Revelations,” where a final conversation with Canotila will complete the “Through the Looking Glass” hidden quest.
