Each stage you visit has different kinds of monsters: monsters at a volcano are strong against Fire, monsters you meet on the sea are strong against water, etc.
Always keep affinity with enemies in mind when forming your party. If you find their weak spot, you’ll be able to do a lot of damage. Taking the right members with you for each stage is the key to success. If you don’t have any allies with the correct affinity for a stage, go and catch some at the Antenna Tower! Perform battles to gain experience to level up your characters. Sometimes, their Antennas may even evolve! Fight to grow and challenge new adventures!
