Great suggestions. It'd be cool to get a bit more variety for SCH and SMN weapons.

As for what's already in the game, the Grimoire Wing from the old Lightning Strikes event is kind of on the "different" side, even though when drawn its overall shape resembles a book. It folds and unfolds like a fan, into a stylized feather-like shape when sheathed, or fanned out to a bunch of feathers forming a book cover, with a holo screen within as the "pages" of the book when drawn. (Did the Lightning Strikes event weapons make it into the MogStation for people who missed the event?)
