Scroll Type for Dragon Parts?

And I just tried every Armor and Accessory scroll I have. Nothing works.

Did you try the generic "Armor" scrolls? They work on any type of armor, that was what was suggested works. I don't have any on me or I'd try (Like I said earlier, they're rare in JMS).

It sucks that they gave these parts upgrades but give you no normal way to upgrade them.
