It has been mentioned to me several times that there is a way to see Red Ring Rico in online multiplayer if you defeat Dark Falz with an specific type of weapon. Some people tell me I need a real flowen's sword, other tell me I need the dark weapons. Can anyone confirm the correct way to do this?

It was also mentioned that there is a posibility that Falz may drop Rico's Ring by following one of these methods, but the chance of finding the ring is as rare as finding a dna flow. Is this true?

Any help is appreciated.
