The process of obtaining the Master Sword in The Legend of Zelda: Breath of the World for Nintendo Switch is very different from other Zelda games, as you can easily beat the game without ever finding the sword.
How to Get the Master Sword in Breath of the Wild | Austin John Plays
Use this guide to find the legendary "Sword that Seals the Darkness" and obtain a powerful weapon that will not break.
The Master Sword is located at the center of The Lost Woods and is protected by the Great Deku Tree, an old ally of Link.
To obtain the Master Sword, you must successfully navigate the labyrinthine paths of The Lost Woods and possess 13 full Heart Containers. Attempting to pull the sword from its pedestal will slowly drain Link's life force, so at least 13 full Heart Containers are required to successfully survive the ordeal.
