If you're like me and explored ahead abit you could do Morrie's monster areana and win

In the mountains where the ship is/was you will find a Jargon the more you head to the
sea. You can also find a Hackasaurus by the starting town. There many others you can find
but you must first do more ranks to find more monsters.
