Yojimbo
Location: Cavern of the Stolen Fayth
To aquire Yojimbo visit the Cavern of the Stolen Fayth beneath the bridge at the northeast ends of the Calm Lands. To get Yojimbo you must fight your way through the cavern and beat Yojimbo in battle. Proceed through the cavern and speak to Yojimbo to negotiate a price for his services. He will offer his lowest initial price if you choose the option, "To defeated the most powerful of enemies." For your first bid, offer half of his asking price plus 1 Gil, so if he ask for 250,000 Gil, offer 125,001 Gil. After his next offer, raise your bid by 1 Gil. By the time he proposes 205,000 Gil, he will generally accept offers below 200,000 Gil, though not much lower. If at any point you offer him triple of his asking price he will give you 2 teleport spheres along with his services.
Unique Attacks: Daigoro, Kozuka, Wakizashi, Zanmato
Yojimbo doesn't have selectable attacks or overdrives. When summoned, Yojimbo attacks based on how much he is paid. Yojimbo's attacks may exceed the 9999 damage limit when Auron activates his ultimate weapon, Masamune.
