If you're playing "Dragon Quest VIII: Journey of the Cursed King," you will stumble across the Monster Arena early in the game. It is located on the southeast continent, southeast of the town of Pickham. You can play a mini-game at the Monster Arena once it has been unlocked. To unlock it, speak with Morrie at the arena and he will ask you to scout three "infamous monsters" for him. Additionally, there are over 80 other infamous monsters that can be scouted; these are not required to unlock the arena. They are distributed on all eight island continents on the world map.
