Planning a way to reach Yu Yevon the Party decides to use the Airship to rip Sin open then enter it.
Cid notices something shine at the base of Sin's Arms and reckons its a Weakspot. He aint far off because that's what the Party must target. Prepare for 3 Battles in a row.
Boss: Left Fin, Right Fin
HP: 65,000 (each)
Overkill: 10,000 (each)
Weak Against: N/A
Immune to: N/A
Absorbs: N/A
Resistant to: N/A
For the most part Sin will remain motionless and sometimes use Negation to cure itself of any Debuffs such as Armour Break and Mental Break.
Tidus and Rikku can get Cid to move closer or further away via Trigger Command.
Sin will only attack physically and with Gravija when you are close by. Characters such as Wakka and Lulu can hit from a distance but everyone else unfortunately has to wait for Cid to move closer.
For an easy Overkill Summon either Bahamut or Anima. If Yuna has her Celestrial Weapon fully powered up then Holy should do the trick.
After the 1st round Cid and Brother blow Sin's Arm clean off using the Airships main gun. Now for the other Arm.
This battle is no different to the previous so just repeat the same process.
After both Arms have been blasted away the main gun gets damaged so its on to Plan B. Jump on to Sin's back!
Here you must face a Sinspawn and another Core located at the back of Sin's neck in between its two Fins.
Boss: Sinspawn Genais
HP: 20,000
Overkill: 20,000
Weak Against: Fire
Absorbs: Water
Resistant to: N/A
Immune to: N/A
Boss: Core
HP: 36,000
Overkill: 3000
Elemental Defences are the same as the Arms.
Sinspawn Genais will come straight out of its shell but will retreat back in after its turn and to avoid the Core's Gravija attack.
Cast Hastega and make sure the finishing blow to Genais does 20,000 damage for an Overkill. Using Bahamut or Anima will make this fight easy enough.
The Core can use Negation to remove Debuffs and when it starts charging energy it means its preparing to use Gravija.
Try to Combo Mental Break and Holy for an easy kill. You only need to do 3000 damage for an Overkill. Keep your HP up and you should be fine.
With the final Core destroyed Sin passes out and crashes into the City of Bevelle. Time for more planning...
