Monster Arena
The Monster Arena is a recurring feature in many Dragon Quest games, especially the Dragon Quest Monsters sub-series, frequently found as part of the Casino.
The DQM version allows the player to enter creatures he has raised in a fighting tournament; the Casino version calls on him to bet a number of tokens on a particular monster, then receives a multiplier (based on odds) of tokens back in winnings, which can then be forwarded to the next round.
Appearances
Dragon Quest III
The original arena is found in Romaria, complimenting the Roman theme to the kingdom. As casino tokens are not in III, players bet gold on their favorite and receive multiples of the bet based on the the winner's odds. New monsters are added to the randomly selected line up at level 10, 20, 30, 40 and 70.
Dragon Quest IV & V
Zenithian trilogy arenas are found in the various casinos, where players will bet tokens to exchange for prizes instead of money. The winning bet is multiplied by the monster's odds as before, with an option to bet the winnings on the next battle.
Dragon Quest VI
Slimopolis replaces the standard arena in VI, where in players can enter one of their bubbly buddies as a competitor. The fights consists of eight ranks with three battles each, for a total of twenty-four. A prize is awarded for each victory, and any completed rank may be challenged again for free (save for rank A).
Dragon Quest VIII
The monster arena is located near Pickham, and is owned by Morrie. After completing his request to battle three infamous monsters, he allows the party to play in his pit.
In the 3DS version, Morrie will join the party as a playable character after beating Rank S and there is also a new rank to battle against. Rank S can be attempted immediately after The Hero and party take care of matters in Arcadia as Morrie mentions needing time to get his friends to arrive.
Additionally, Morrie can't be leading the party when in the Monster Arena as he will be in his usual place and can only revive fallen monsters when at the Arena.
