Scattered throughout Termina are five Great Fairy Fountains, each requiring you to collect 15 Stray Fairies from a specific dungeon. Returning all 15 to a fountain will grant you a powerful upgrade, such as increased magic capacity, a stronger spin attack, double defense, or the Great Fairy's Sword. These upgrades are permanent and significantly boost Link's capabilities, making them highly worthwhile. Prioritize collecting Stray Fairies in each dungeon.
