The Legend of Zelda: Breath of the Wild community has discovered a glitch that allows players to obtain the Master’s sword at the very beginning of the game almost immediately after training.
In the video, Limcube talks about an exploit first discovered by the speedrunner Bot_W. He notes that this is not the only glitch allowing players to gain early access to the Master’s sword. However, it is much simpler than previous finds, so it should be easily achievable for the average player.
To take advantage of this bug, you only need to go to the sword sanctuary in Korok forest with the materials for building a fire – this is one piece of wood and flint. You will have to light the fire pretty close to the sword itself, but as soon as you do this, just put Link between the fire and the sword, look at the cherry blossoms over your head and use the command “sleep until morning.” During the loading screen, press the A button as quickly as possible, and when you wake up, you should have the Master’s sword.
The official method requires Link to accumulate 13 health hearts. As noted by Limcube, this glitch allows you to get the sword almost immediately after exiting the Great Plateau.
