It's Destiny Islands! And the best way to beat Riku in this fight(thank god it's the last), have plenty of value 0 keyblade cards...don't fill your deck with them ,but have about...5-8 Kingdom Keys of value 0. When He's about to use a sleight, use one of those value 0 cards. He'll use both his Elixirs in this fight after 10 sleights. And if you can keep following this strategy for about...10-30 minutes, you'll start to notice that he's running out of cards.. that's the opprotune moment to beat the living hell out of him. When you run out of value 0 cards anytime during the battle, immediately reload, do nothing else. This is the long way out, but it works.
