Sin Boss Fights

Sin Boss Fight

Left Fin Boss Battle Guide

Easy battle, Command the ship to go in. Use Auron's Armor Break to remove its armored status then use Tidus Hastega. Hack at it and use Rikku's Al Bhed Potion to keep everyone's HP up from Sin's Team wide Physical attack. Pull back when it starts to charge its core to avoid its Gravija which deals 3/4 of everyone's current HP to themselves.

Right Fin Boss Battle Guide

Same Strategy with Left Fin. Right Fin will use Negation as a counterattack now so prepare to reapply buffs and debuffs in the fight.

Sinspawn Genais and Sin(Core) Boss Battle Guide

Genais and Core Boss Fight
Genais starts the battle outside of its shell and uses Venom. Once enough damage is done, it will hide in its shell and use Sigh that inflicts blindness and damage to all allies. Genais will also retaliate with Cura when it is damaged.

Sinspawn: Genais and Sin(Core) Strategy

Keep damaging Genais and burst it down with overdrives to avoid a lengthy fight. Once Genais is down, use armor break on Sin and keep attacking it to end the battle quickly.
