The unbreakable Master Sword is one of the best weapons in the game. It cannot be damaged and does not have a durability meter. However, it does have a cool down period before it can be used again in combat after it has been depleted of its charges. The Master Sword can be found in a grove inside the Great Hyrule Forest, northeast of Central Hyrule. To reach the area, go through the Woodland Stable and continue on the path until you reach the Lost Woods. Then, travel towards the Korok Forest. While at the entrance to the forest, light a torch at the nearby brazier. The torch flame will tilt in certain directions; follow the directions of the flame. However, the forest is filled with fog that can teleport you back to the start. Whenever it seems to be thickening around you, retrace your steps back a bit to avoid the fog. The flame will eventually guide you to where the sword is stuck inside a stone. To collect the Master Sword, you will need 13 heart containers.
