Minimum weapons to kill Ganon (Minor BotW Spoilers)

This is a bit of a silly question on the surface because each weapon has a different damage value and number of uses. You could easily get away with a single weapon if it has high enough damage and durability, especially if you supplement it with attack-boosting effects.

But the actual (somewhat more interesting) answer to this question is zero. You can go into the Calamity Ganon fight with no weapons at all and still win. This because of two things:

• Shields. As long as you have a shield and good timing, you can reflect the Guardian Beams.
• Bombs. Even if you have no weapons and no shields, your infinite supply of bombs will eventually get the job done. (It'll take forever though.)
