In the Argentum Trade Guild on the Goldmouth Flight Deck, there's an Informant named Mumufa. One piece of information he sells is "Stench" which says:
Stinky Drivers repel their Blades. Too far and specials become impossible.
I understand the second part means specials can't be used when you're far from your blade, but what about the first part? Are stinky drivers actually a thing? Or is this just flavor text?
