The Master Sword is the only truly unbreakable weapon in the game, but there are a few other items that can either be reforged, or that have a very high durability stat. This is as close as you’re going to get to weapons that don’t break, so make your peace with that and go get ’em.
Can the Master Sword be destroyed?
Unlike the vast majority of other weapons, the Master Sword becomes depleted of energy instead of breaking. This means that, as long as they don’t mind a short wait, players are able to freely battle with the Master Sword without any worry about destroying the precious artifact.
Does the Master Sword have infinite durability?
The Master Sword is one of the most powerful weapons found in Zelda BOTW. Its durability is infinite as it never breaks.
The Master Sword is a 30 strength Sword, but will deal out much more damage to Ganon and anything affected by the Calamity, making it a useful weapon against major enemies and the end game.
