  I said there are no Items, but there are a lot of them, they are just pretty hard to get and it will take you a lot of time and practice to get them. First of all, I'll tell you about how the Monster Arena works. 
  On the east side of the Calm Lands, you will be able to meet the Monster Arena Owner. He will ask you to capture the monsters on the loose and you will be able to buy weapons with the Capture Ability from him. With those Weapons Equipped, you will Capture every monsters that you fight. There are exceptions though, since you can't Capture Bosses and Mechanical Monsters. You can capture a maximum of ten monsters and once you have captured specific monsters in different areas, you will unlock Special Bosses to fight at the Arena. Make no mistakes about it, those bosses are hard to defeat and it will take great characters to defeat them. You should hit more than 50,000HP with your characters, it will make those fights a lot easier. Now, here's the list of every enemies you can capture in the game and the area where you can capture them and how many Gil it will take you to fight them. For more information on those monsters, look in the Bestiary at the end of the FAQ.
