Go to the Withered Ruins, which is near the town of Miera. Go towards the back end of the ruins. When a battle against a Gagison comes up have Tim use "Divide" on it. Make sure he is only using "Divide" on the Gagison or this trick will not work. The Gagison will turn into a Hyulkonton. Be careful, because they have 64,000 health (hit points) and have two moves that can place a lot of status changes on your characters. They are well worth the fight, because they are worth 30,000 experience points and 50,000 gella. If you use a Lucky Card, those numbers will double.
