  This gigantic monster launches Sinscales to engage the party
on the deck, which are replaced by new Sinscales for each set
of three you eliminate. The real target is Sin's gigantic fin.

  Although you start with Kimahri, Tidus, and Yuna in your party,
you can replace Yuna with Lulu and cast any spell on the giant
fin. Then, using Tidus and Kimahri, kill only two Sinscales.
Leaving one Sinscale alive lowers the amount of damage the
party will take during the battle. You can then switch out
Kimahri for Wakka, and bring Yuna back in to heal characters
who need it. Wakka, Lulu, and Kimahri are the only characters
who can damage Sin, in addition to Valefor if Yuna Summons it.

  Summon Valefore as the battle comes to an end. Use physical
attacks to help fill its Overdrive gauge. The aeon's Energy Ray
or Energy Blast attack will most certainly end this battle.
