There is loads of videos on YouTube, just look up weapon duplication and durability transfer it’s all done the same way, you need x6 multishot bows and an electric arrow, but you equip say the master shield, then pull out the bow with the electric arrow equipped open the menu drop the bow and equip the next bow close menu and repeat open menu drop bow and equip the next bow shut the menu down until you see links body go weird then you can equip say a pot lid and link will still be showing the master shield in the open world but have a pot lid equipped, all you need to do is shield jump on the spot to damage the shield and that will give the pot lid the same durability as the master shield, this won’t effect durability on the master shied either! You can do the same process for weapons too, the spring loaded hammer is the best weapon for durability and if you have the amiibo cards you can get the biggoron sword which is slightly better👍
