Taking on the challenges that the various arenas inDragon Quest Monsters: The Dark Princehave to offer is a very rewarding experience. While you don’t get all that much in terms of tangible prizes, victory serves as a testament to your teambuilding talents and monster synthesis flair.
The Maulosseum is home to a number of deadly challenges, and you’ll be forced to take on a few of them as you progress through the game. It’s Dragon Quest’s way of making sure you’re ready to progress to the next level of difficulty. While Category G is all you need to pass to begin with, Category F will rear its ugly head soon enough.

Maulosseum Rank F Overview
Entry Fee: 50 Gold Coins
Three battles await you in this arena gauntlet, and you’ll have tobeat them all in succession. You’ll get healed between rounds, though, so don’t worry about your monsters going all out!
Hunter Mech
Stabosaur
As in Endor Colosseum’s F Category, the big threat here is theLarge monster in the third round. TheHunter Mechis a tough cookie with some very high-damage physical attacks, and its backed up by two other decent monsters, too. In addition to that, the second battle can prove tricky - the very large monsters here have quite large health pools.
To sum up, you’ll want a team that can both take a lot of damage but also dish it out -this arena gauntlet is a battle of attrition, and you’ll need to whittle down the enemies before they can do the same to you.

How To Beat Maulosseum Rank F
This is an arena wherebuffing and debuffing moveswill come in handy. It would be a good idea to build up a monster that has the Oomph, Kabuff, and Sap moves.
A particularly good monster for this arena is theSnail Slime- itsBarricadeTalent gives it very early access to Kabuff and it’s easilyfound in the Circle of Caprice during Winter. Its cousin, theShell Slime, can also learn Kabuff throughDefender, and is easily synthesised. If you manage to get some other useful status moves on either of these slimes, they’ll prove extremely useful.
Be sure toset your buffer to ‘Support Your Allies’in the Tactics menu!
In addition to a buffer (preferably with Kabuff), making sure you’re using ateam with naturally-high defenceis a good way to survive the onslaught that is the third round. Avoid using squishy wizard-type monsters - they are more likely to fall quickly and end up useless. Instead,bulky physical attackersshould be preferred.
Two offensive moves will prove extremely useful in this fight:Dragon Slash and Matter Scatterer. The former will destroy the Jargon, Killer Gila, and Stabosaur, while the latter handily takes care of the Erazor Blade and Hunter Mech.
Bang Afficionado (Airbagon)
Materialist (Eggsoskeleton)
Synthesising a high-attack monster that has both of these skills would be a great way to take care of lots of threats at once - the game is pretty good at choosing the right moves to deal maximum damage.
Matter Scattereris the important one to get here - dealing with the Hunter Mech as soon as possible is key to success, especially as its allies like to buff its attack, making it even more deadly.
Overall, as long as you’ve been diligently experimenting with synthesis and making sure you’re scouting the latest monsters, you really shouldn’t have many problems with this category. The Hunter Mech can be a pain, but you have access to plenty of tools to defeat it.
Winning will unlock the next Category, and this is one you’ll have to face before you can progress the story.
