Do you get an extra slot for the master sword?
I was playing Legend of Zelda Breath of The Wild. I got 13 hearts and I went to the Korok forest; I had 2 empty weapon slots. I pulled out the Master Sword but I still had those two empty weapon slots. I know that the Master Sword has its own slot but the thing is, did the Master Sword take one of the two spots and gave a new one or did the Master Sword come with its own spot meaning the Master Sword did not go in those two empty slots?
The Master Sword has its own hidden slot, which can't be used by another weapon. So it was never accounted for in your two free weapon slots.
