How to Use Rusty Weapons in Hyrule Warriors: Age of Calamity

Just because Hyrule Warriors: Age of Calamity is set before the world went belly-up, that doesn’t mean there aren’t plenty of rusty weapons lying around. After all, if you try to logic out the timeline, there was plenty of major stuff going down before the Calamity was even a legend. But what can you do with these scraggly relics? Here’s how to Use Rusty Weapons in Hyrule Warriors: Age of Calamity.

How to Use Rusty Weapons in Hyrule Warriors: Age of Calamity

At some point in the game, you’ll start obtaining rusty weapons alongside your usual cache of post-battle rewards. There’s no surefire way to make them appear, though you do seem to have a higher chance of getting them for the character you were using. The Hylian blacksmith can restore them to fighting condition, but you’ll have to do him a favor first.

After you complete “Freeing Korok Forest” in Chapter 3, a new quest will pop up on the map next to the Hylian Blacksmith’s Guild. This quest, entitled “From Rusty to Trusty,” requires an investment of the following materials:

• 1 Octorok Tentacle
• 1 Octorok Eyeball
• 2 Octo Balloons
• 10 Octorok Trophies

With these materials, the Blacksmith will discover the secret Octorok technique for de-rusting weapons! Because… Octoroks eat rust, I guess? Anyway, with this, Octo-Polish will now be available in the Blacksmith menu.

To de-rust a rusty weapon, select Octo-Polish at the Blacksmith’s, the character holding the rusty weapon, and the weapon itself. When you’ve got the weapon loaded, you’ll need to contribute some materials to the restoration process, as well as pay a nominal fee. You have to provide a set number of any material from the following three categories:

• 5 Minerals 
• 30 Monster parts 
• 100 Trophies

Feel free to mix and match offerings from your stock of materials. Whatever you have in the highest supply, usually minerals like flint and parts and trophies from trash mobs like Bokoblins, are probably the best call. 

With the supplies supplied and the fee paid, the Blacksmith will restore your weapon to its former glory! Now, the downside is that there’s no way of knowing what weapon it’ll be until you actually restore it, but in my experience, rusty weapons almost always yield weapons with very high base stats. Heck, the first time I did it, I got a Royal Sword and a Royal Halberd for Link, two of his strongest weapons on par with the Master Sword! Even if it’s a gamble, it’s most assuredly a worthwhile one.
