Mended? So patched onto something that already exists? Huh, alright...

[Yoon wanders off with that information and eventually comes back with something that isn't... acid-proof, but it's magical clothing.]

What about something like this? A coat of many colors? There's a bunch of different stories about it... some books, some theater plays, and even a song or two. Maybe one of the versions or one of the patches is acid-proof.

[Since hey these are just stories as far as he's concerned. Folklore is wildly different.]
