Sin is a monster from Final Fantasy X that has roamed Spira for 1,000 years with the sole purpose of destruction. The Maesters of Spira spread the rumor that the only way to permanently destroy Sin was to rid the world of all machina. The only way to hold off Sin for a while was to make an ultimate pilgrimage. A Summoner must go to the ruined city of Zanarkand and offer one of their guardians to Lady Yunalesca, an unsent summoner who first defeated Sin. Yunalesca would transform the offered guardian into the Final Aeon with the power to defeat Sin. The Summoner must then fight Sin at the Calm Lands. The shell of Sin would be destroyed by the Final Aeon. Unfortunately the Summoner who called the Final Aeon must provide it with their life force, killing the Summoner. Additionally the guardian who was transformed into the Final Aeon would get possessed by Yu Yevon. After the Final Aeon destroys Sin there is a period of Calm, the time Yu Yevon recreates Sin from the Final Aeon, before wreaking havoc in Spira again.

[edit] Sinspawn

Sinspawn are creatures that Sin has created, you fight various species of these through the game, the first boss battle is against a Sinspawn. You fight one soon after meeting Yuna and the guardians, another is then fought just after the first battle with Sin, under water, then again twice at Mushroom Rock before a final fight against one alongside Sin.

[edit] Inside Sin

Sin also serves as a location in FFX. Inside Sin there are various creatures, many that look similar to other fiends around Spira and some that are found in Omega Dungeon. You also have a battle against Seymour inside Sin, and of course with Braska's Final Aeon and Yu Yevon.

[edit] Boss Battle

Throughout the game you fight Sin numerous times.

[edit] SS Liki

Sin

Sin is first encountered while the party is on board the SS Liki.

[edit] Strategy

Generally, unless you've spent plenty of time on the Sphere Grid, your attack options are limited. Tidus and Yuna are unable to attack Sin, unless Tidus somehow already has Blitz Ace. Kimahri can only attack with Lancet. Wakka's Blitzball attacks and Lulu's spells are able to reach Sin, as are any of Valefor's attacks.

If you choose to fight Sin with normal characters, it's best to attack some Sinscales. Ideally, you'll have Wakka and Lulu. If you think they might need some extra HP, Yuna can accompany them. Otherwise, Tidus' Cheer makes things easier. Don't kill them all or three more will land on the ship. Sin has no attacks and is not a direct threat to your characters. Once two Sinscales are gone, it's basically about attacking Sin and having adequate HP.

Another option is to summon Valefor. It's best to do it after taking out two Sinscales. Get Valefor attacking Sin until her Overdrive gauge is full; the Sinscale contributes. Finally, unleash an Overdrive on Sin. If his HP is below about 1,050, this should result in an Overkill.

[edit] Left Fin

The Left Fin is fought from the deck of the airship as the party attempts to enter inside Sin.

[edit] Strategy

Before even thinking of taking on sin, make sure that you save, and do not use your overdrives until later unless you already have Anime or the Magus Sisters. This is a relatively easy fight as long as you heal after gravity, it shouldn't be too tough, just long if you don't have Anime or are at a high level.

[edit] Right Fin

The Right Fin is fought immediately after defeating the Left Fin.

[edit] Sin's Core

Sin's Core is fought during the boss battle with Sinspawn: Genais.

[edit] Overdrive Sin

Sin's Head

Overdrive Sin is the final battle with Sin, fought on the deck of the airship.

[edit] Strategy

Overdrive Sin is a really tough fight if you haven't gotten anime, so be prepared with aeons all at overdrive, because it can't be hit melee until you get close enough, and by that time, you have around 2-4 turns (of his) to deal some damage before his overdrive charges up and annihilates you. Make sure that you only use offensive skills, because Sin doesn't have any attacks at all, and his overdrive charges up only on his turn.
