Don't you just hate it when that ball falls down in the middle of a good combo? Well here's a solution get that score way up into 10,000s. First, set your shortcut menu so it has thunder in it. Then equip Berserk Charge as an ability. When you go to the minigame, first use thunder until your magic runs out. Then keep attacking the ball while your MP charges. When it finishes, drop to the ground and repeat the process.
