Monster Arena

The Monster Arena is a Battle Arena in 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.

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

Profile
Once the monsters are caught they can be battled at any time within the arena for a fee. If certain conditions are met 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 costs. The most expensive battle is against Nemesis, costing 25,000 gil each time. Within the arena, the player cannot get a Game Over after defeat: they simply return to the entrance and can heal, and then try again.

A lot of the Monster Arena monsters' equipment drops are semi-fixed. Some monsters, including all original creations except Neslug, drop equipment that provides a 6% critical hit chance bonus instead of the usual 3% (this is relevant to weapons and armors, but only to attacks that deal physical damage).

Monster Directory
In the monster directory there are 13 different sections. These are the different areas in which monsters can be found. The areas and monsters in them are shown below.

Some monsters appear in more than one area, however, for capturing purposes they count towards the same area regardless of where you find them. For example, a Nidhogg captured on Mt. Gagazet still counts towards Cavern of the Stolen Fayth. In most (but not all) such cases, the fiend counts towards the first area where it can appear.
