What to Do with Rusty Weapons

How to Obtain Rusty Weapons

Rusty Broadsword

You will sometimes start to acquire rusty weapons around the middle of the campaign. Rusty weapons can be obtained from rewards and chests in battles, but they cannot be used in battle as is, and will show "???" in place of the level and attack damage.

Rusty weapons will always have Rusty in their name, but the icon beside the name determines the type of weapon you'll receive after de-rusting.

Upgrade the Blacksmith

To de-rust rusty weapons, you have to first unlock the Hylian Blacksmith Guild. Afterwards, upgrade the Blacksmith by completing the quest, From Rusty to Trusty.
