Concidering in both games depending on your choice of playstyle, would determine which of the 2 final keyblade you need. The ultimate Keyblade best in physical dmg, have to build it. Or the magic one, enhances magic, only can get if beat seph. Lol first game I went magic.. kind of messed up and made the solo battles near end of KH1 very hard for me. Though KH2 wasn't so hard loved using anti-sora.
