Cave of Ordeals

Found in Gerudo Desert, this large cave is made up of 50 rooms, most housing a set of enemies (every ten rooms there is a Great Fairy that will release healing fairies into one of the four springs). These enemies get progressively harder as Link progresses through the cave. Every 10 floors, fairies are released in the springs of the Light Spirits. The final prize is Great Fairy Tears and the releasing of Great Fairies to each spring, where Link could get a bottle of Great Fairy Tears whenever he wishes as long as he doesn't already have some. The Cave of Ordeals is very similar to The Wind Waker's Savage Labyrinth and is incredibly difficult.
