| Strategy | |||
| Natus alternates turns with Mortibody and the battle is divided into three sections in terms of attacking patterns. Start with Yuna, Tidus, and Auron. Tidus and Auron can speak with Seymour to augment their Strength by 10. As soon as all three characters achieve a positive status, Desperado will be used. Have Yuna first use her Trigger Command to raise her Magic Defense by 10. Have Tidus use Haste on Auron, or better yet Hastega for everyone. Exchange Lulu for Yuna and have her cast Bio on Natus (Mortibody's immune). Have Auron and Tidus physically attack, then bring Yuna back in to Grand Summon Bahamut. Use Mega Flare to deplete Seymour's health and hopefully kill the Mortibody. Bahamut will then be banished and Natus'll either use Break to petrify, maybe just use a Multi Spell, or possibly Flare for heavy damage. Heal after this. Have Tidus next use Slice and Dice, then Auron should use Shooting Star. Yuna then should summon any other aeon, whose Overdrive (preferably Shiva's Diamond Dust) gauge is full, causing more heavy damage or it may be enough to take Natus and Mortibody (if it's still in the battle) out. Otherwise heal with a Mega-Potion if he uses an elemental attack you haven't protected against, after Yuna's aeon's been banished. Finish the battle by repeating this strategy if neccessary. | |||
