Monster Arena

The Monster Arena is a Battle Arena located in the game Final Fantasy X, situated in the Calm Lands. The Monster Arena is used to store fiends caught during the game. This is done by defeating the monster while using weapons with the Capture special ability, which can only be purchased here.

Once the monsters are caught they can be battled at any time within the arena for a fee. If certain conditions are met then new creations are bred and can be fought. As new monsters are bred, the owner rewards the party with special, and often rare, items. For each new creation the first battle is free, but any fight after that has a cost. The most expensive battle is against Nemesis, costing 25,000 gil each time. Within the Arena, the player is not in danger of receiving a Game Over after defeat: they simply return to the entrance and can heal, and then can try again.

In Final Fantasy X-2 the Monster Arena becomes Clasko's Chocobo Ranch.
