"To de-fog and charge your newly acquired cloudy mirror, talk to the mother and
son at the entrance of Macalania Woods. Find the father at the campsite,
speak to him, and he'll run off to be reunited with his family. Go back to the
entrance and speak with the mother and father again, and keep talking to them
until they mention their missing son. This may take 3 or 4 tries. After they
mention their son, head up the sparkly path to their left into the trees. Bear
north at the first fork, where the son should allow you passage if you talked
to his parents enough times. Show the Cloudy Mirror to the large ambrosia
salad-looking plant, who'll turn it into the Celestial Mirror. If there's a
woman blocking the path instead of the son, either a) you're not far enough
in the game yet, or b) you didn't talk to the parents enough times. With the
Celestial Mirror, you can now open chests and detonate the mandalas
protecting your ultimate weapons."
