Early bosses like Sinspawn Ammes, Lord Ochu, and Sinspawn Gui serve as tutorials for core mechanics. For Sinspawn Ammes, use Tidus's attacks. Lord Ochu is weak to Fire, so use Lulu's spells. Sinspawn Gui requires breaking its arms with physical attacks before targeting the body. Remember to use your Aeons for Overdrives and to absorb powerful attacks. Always keep your HP up with Potions and Yuna's Cure spells.
