Strategy

How to Defeat the Bosses

Focus on taking out Sinspawn Genais before directing attacks at Sin’s Core. Sinspawn Genais is weak to fire, so doublecasting Firaga allows you to easily burst down its HP. Use NulTide to defend against Genais’ Waterga counterattack. Avoid attacking Sinspawn Genais with water spells or weapons with Waterstrike, as it will heal it instead.

When Sinspawn Genais has been dealt with, aim for Sin’s Core. Be sure to have Rikku ready with healing items, especially Al Bhed Potions, as you are likely to get hit with Gravija at least once during the fight. Tidus should use Hastega to get in more turns before the boss can act. You can also lower its physical defenses with Auron’s Armor Break. Keep attacking Sin’s Core with physical attacks until it is defeated.
