how u get gillionare on ur weapons...

Customoize a weapon with 30 Designer Wallets.

You could also get Rikku's celetsial weapon and power it up with her Mecury Crest and Sigil and it has Gillinoiaire...

yes but iznt rikku horrible?

How dare you day something like that??? Rikku is awesome with her Mix comands ::coughtrioof9999cough:: and she's very fast, thus allowing her to take up any art and being actually better than to original ones due to her higher agility...

whoa u took it a lil serious there
