Vorban is an enemy in Final Fantasy X. It can be bred in the Monster Arena in the Calm Lands after the player has captured at least one of each fiend from the Omega Ruins. The party will acquire 60 Designer Wallets for unlocking it, and it costs 6,000 gil to fight. It shares its model with the Barbatos.
Vorban is a tough opponent because of its high HP, high Defense, and its immunity to Armor Break. It can randomly counterattack with Mortar, which hits the party for moderate damage, and can use Body Splash to attack the entire party.
To start the battle, it is a good idea to cast Shell on the party. For offense, magic works well to take it down. Overdrives can be helpful as well. If the player has Anima or the Magus Sisters, this fight becomes much easier. Celestial Weapons ignore targets' Defense, and will quickly decimate Vorban.
