Thanks for the quick reply. It seemed to me that it was a setup for something that perhaps they dropped for some reason. Toady says something like "it's too rich for my blood maybe my big brother can handle it." Also, Irc there is no other equipment like this in the game. You can still fuse all of Jaster's Unique swords for example. Once to their final upgrade you can still fuse them with crystals to master their elemental stats. It seems weird, an oversight perhaps?
