First take out the Sinspawn or it will absorb the attacks for Sin. Use Hastega
on youself then use Slow and Silence, Reflect if necessary ON the enemy to
prevent it from healing itself. Kill off the Sinspawn and advance. Now take out
Auron and use Armor Break. Have him use physical attacks and have Lulu use
Doublecast using Flare or Ultima. Copycat it if possible. If not use Holy or
Just continue this, healing with Items mostly. Refrain from using lots of
Healing Magic which reduces your MP use, as you will need it after this battle.
Kill it off fast and you will fight the head.
================================================

Sin's Head has the most HP you will ever see in the game, besides the Monster
Arena super enemies. After the long scene head to the top of the ship again.
