About Exotic Blueprints. Do they only apply to normal exotics? Can people "cheese" special exotics? Weapons from Vanguard Missives or Prison Ciphers, I could get one and then have three without doing any more bounties or arenas than I have to? A three for one Thorn deal? Mythoclast? Three Necrochasms from a single Crux? Clarification please.
