Hm. Yeah, I can see why they might've done it, restricting you from wearing two. Can agree, it should've been a 1:1 basically identical item to the belt, adding the unique tag is problematic. Make it a choker or something.

Damn, that's really gonna suck since this seems like something they're unlikely to change. Simplest option at this point is maybe like you said, just have Arthro keep dropping the belt as a token, and add in a trade within Pagos.
