Yeah I agree with the whole block situation. And as for the prize pods in Olympus Coliseum, they're in that left corner. The Mirage Arena is pretty challenging yes but perseverance is key okay. Now you will have to get ready when you fight the challenge called Villains Vendetta. I beat that challenge on the PSP version (since I didn't have the Final Mix before that was the last challenge) and since I did everything before that I finally got the Ultima Weapon.
