First obtain the Magic Armor by purchasing it from Malo Mart. Have plenty of bottles full of potions to keep your hearts up since they’ll probably run out by level 45. Also keep one or two fairies in the bottles so they revive you when you die. Use the ledge to your advantage and try to pick off monsters with your arrows. Make sure to pick up arrows so you keep your quiver full. You can also try beating this place without the Magic Armor, but it’s much more difficult.
