Hrm.. you know what? Digging around in the files, I can't find *ANY* recipes that use this item. Even FC Crafting for the 4 new Airship parts doesn't use it.. Interesting.
For now, it appears as if this item is useless! Maybe we'll get a hot fix for something using this item.. Like, maybe there'll be new craftable PvP gear coming with The Feast that will use this.. that's the only thing I can guess at.
