How do you beat the cave of ordeals?

Simply by defeating all monsters in all 50 floors. No time limit. No restrictions or conditions. Just fight, fight(use a potion if you want) and fight some more. It's easier on Wii (in my opinion) than on Gamecube so all gamecubers watch your step carefully. Use a variety of techniques and make sure that you have finished the "City in the sky" before attempting to defeat the Cave of Ordeals because you neeed all dungeon items to go through the 50 floors.
