I know you figured out your Blizzard 2, but I just wanted to let you know that your Limit Break, and eventually Freeze spell, have a special method of Targeting where you have to select a spot on the ground for the AOE to take effect. When you try to use it, a blue glowy dot will show up in the center of the screen. You can move this dot (and the spot on the ground) with the right stick and when you have it placed where you want (it will turn orange at a spot that's ok) you just hit X to activate the spell or limit break.
