Instructions
Raise your Digimon's spirit, attack and defense stats. Getting these stats to a high number will keep your Digimon strong. Fight in battles to gain experience that will help your Digimon grow and increase in level.
Feed the Digimon fruits and give them other training items. These can be found throughout the game by winning battles, harvesting them on your farm or purchasing them in the farm shops.
Digivolve your Digimon. As they progress from their "baby" forms all the way through their "ultimate" forms, they will increase in strength and become more useful.
Degenerate your Digimon once you reach "Silver Tamer" status. This is the process of reverting your Digimon back into their younger forms. Take the young Digimon with you to fight in tough battles with more experienced Digimon and they will increase both in strength and aptitude.
