As someone who hasn't played the game yet is it possible to just collect/buy a lot of the fragile swords and keep them stocked up especially for dungeons?
To be honest, there's no point worrying about weapon durability because the moment you drop off the Great Plateau, you're swarmed with items. People complained about the "your wallet is full, so let's put it back" notifications in Twilight Princess, but I've had several times more "Your inventory is full." notifications in BotW when trying to pick up shields/weapons than I did those TP notifications, or even the Skyward Sword notifications with item descriptions for items you've already collected. That's how often the game throws stuff at you to prevent weapon durability from ever being an issue. It's not even an issue in Master Mode where enemies get health regen and are all upgraded by one tier at the start of the game, at least it wasn't for me.
So if I go ham on destroying enemy in sight, as long as I'm constantly picking up stuff I'll be good? ---
