Oerba (300AF) - Tile Trial Puzzle Guide
Down by the beach area of Oerba (300AF) you'll find another yellow glowing time paradox. Step inside for a set of tile trial puzzles. For the first puzzle, immediately turn left, looping around to grab the final crystal from beside a white tile, on which you can step twice. On the second puzzle, take the first right you can, grabbing the crystal there before going back to the start of the puzzle and getting the crystal in the bottom left. Snag the last two crystals in the top left, then exit to get Fragment of Time #61 - Astonishing Limestone.
