Shuyin (boss)

Shuyin is the final boss of Final Fantasy X-2, fought after defeating Vegnagun. His attacks are all the same as Tidus's Overdrives in Final Fantasy X (albeit with different names), and all deal heavy damage to whomever they hit. It is best to heal whoever gets hit by Shuyin while having the other two party members attack Shuyin full force. The best strategy is to use Light Curtain on the party to protect since Shuyin's overdrives are powerful enough to take down anyone of your members. It would also be wise to steal the extremely rare Hero Drink item from Shuyin.
