How to beat Seymour Flux
Ok guys. I had trouble with this one for a really long time, but then I figured the easiest way to beat him. First, make sure that all of your characters and Aeons have full Overdrives, ready to go. Also, you need at least 2 Underdog's Secrets. It does not matter what three characters you have in the top 3, but one of them HAS to be Rikku. Your very first move is going to mix those Underdog's Secrets, which makes the item "Sunburst". Sunburst will cause 19998 damage, therefore weakening Seymour and the Mortiorchis substantially. Then, just start wailing on him will all of the Overdrives. The reason you need the Aeons in overdrive is because Seymour will cast a spell called "Banish", which instantly KO's your Aeons. This goes so fast that he doesn't even have time to launch a Cross Cleave or Total Annihilation. Good luck to all you guys out there!
