I've just gained enough BP to get the omnislash and w-summon, bought them, but now when i go to the desk i still get the same message as before: "register for battle?..." I wonder if there is a certain amount of times i need to fight regardless? Also, can you leave the battle arena after you've bought the 2 items and then return to fight the special battle, or do you have to do everything in one visit ? thanks. btw that sounds lame about the FF9 guide..
