Final Fantasy III/Sealed Cave

When you enter the Sealed Cave, you find yourself in a large chamber. Walk straight ahead, and follow the curving path until you arrive at a two-way split. Keep traveling forward to find a chest (Potion), then return to the split and take the other path to travel deeper into the dungeon. Follow this path until you reach a path that leads off into a small chamber with a chest (Cure magic). After this, continue to follow the path to a set of stairs.
