- —At the start of the battle
Shuyin has high Agility, Evasion and Strength, and good Defense, but has mediocre Magic Defense and poor Magic. His attacks resemble Tidus's Overdrives in Final Fantasy X (albeit with different names), and deal heavy damage. He cycles through them, throwing in regular attacks in-between. Terror of Zanarkand will probably K.O. any character. In the original version, Shuyin favors Yuna, and if she is alive, he'll target her above the others. In the remastered versions, he'll target any party member.
The girls should be equipped with dresspheres that deal high damage, like Dark Knight and Samurai; stat-increasing accessories and Garment Grids, like Rabite's Foot (increases Luck) and Iron Duke (increases almost all stats), and Valiant Lustre (increases stats by 20) and Higher Power (breaks HP and damage limits). Warrior, Black Mage and Berserker are also good choices due to their damage-dealing potential, but they all must be equipped with accessories and Garment Grids that boost Strength, Defense, Magic and Magic Defense—the latter two for the Warrior, the former two for the Black Mage, and the latter three for the Berserker. Black Mage, Dark Knight and Samurai should wear Haste-inducing accessories, like Speed Bracers. The Mascot is also a good dressphere if the player has it, due to its high stats.
The player should also have a White Mage or Alchemist for healing. In the original version, Yuna should not be the designated healer. In all versions, the player needs to heal whoever gets hit by Shuyin while having the other two party members attack full force. A good strategy is to use Light Curtain for Protect and Lunar Curtain for Shell on the party. It would also be wise to steal the extremely rare Hero Drink item from Shuyin.
"Their Resting Place" plays during the battle with Shuyin. The theme includes a dark reprise of the melody of "1000 Words," the game's vocal theme that Shuyin's lover Lenne wrote as her last song to him, but which he never heard.
