The world of Zelda: Breath Of The Wild is filled with Rusty Broadswords, but using them won’t do you any good since they are pretty weak for when fighting most enemies since their durability is very, very low. You can do lots of damage, but the sword will get broken extremely fast.
Luckily, there’s a way to upgrade your Rusty Sword in just a few simple steps. Articles editor at Dorkly, Tristan Cooper, posted a video on Twitter, explaining gamers how they can upgrade the humble Rusty Broadsword.

All you have to do is to obtain a Rusty Broadsword, locate an Octorok, and Allow the Octorok to vacuum up your Rusty Broadsword. It will then spit it back out, and it will no longer be a Rusty Broadsword but a Royal Broadsword. Simple and effective.
The above guide also works for Rusty Shields, with Tristan confirming a rumor that allowing an Octorok to vacuum up damaged weapons could repair them to be false.
The guide is a great way for new players to acquire a powerful weapon during early game, and it only asks for a weapon that can be found pretty much anywhere.
