In Koseki Village, under the cliff where the Statue of The Seven stands, you’ll find a Light-Up Tile puzzle accompanied by a Stone Tablet. Interacting with the Tablet will give you a clue: And that which is different shall be illuminated all the same. It’s the hint to solving this two-faceted puzzle.
Start by heading to the exact area marked on the map below.
Apart from a Light-Up Tile puzzle and a Stone Tablet, you’ll also find a Phase Gate standing on a nearby rock. Head to the Phase Gate and allow it to fly you a couple of islets away, where you’ll find another set of Light-Up Tiles, but with three Tiles already lit up.
Remember which Tiles have been lit up, then use the Phase Gate to head back to the first puzzle’s location. Here, you must activate the Tiles that were not lit up in the second set.
Reference the image above to find all the Tiles you need to step on in any order. If the wrong Tiles were lit up, simply step on them again to deactivate the lights.
If any other Tiles apart from the six above are lit up, the puzzle will fail. However, once you manage to light up just the six above, an Exquisite Chest will appear.
