Water Temple (Ocarina of Time)

Deep under the vast Lake Hylia lays an ancient temple known as the Water Temple. It requires the use of the Iron Boots to get to its entrance gate and the Hookshot to simply open it by shooting the target above. While it is not necessary, the Zora Tunic allows Link easier access through the temple. Its enigmatic structure consists of various levels and requires the use of playing the Zelda's Lullaby to each of the Lion-type markings on the walls. You will need to use all your intellectual skills and cunning surviving techniques to truly conquer this temple. This will be hardest temple you have come across yet and possibly the hardest in the entire game. Be very aware of your surroundings since you never know what to really expect. You shall also come to confront your very own shadow-self sometime while progressing your way forward.
