Instructions
Take your Digimon to your farm and leave them there for training. If you are trying to raise the spirit level of an egg, you can leave it at the farm, too. Digimon farms are places where Digimon tamers can leave their creatures for long stretches of time to help boost their stats without sending them into battle. You start out with one, but have the option to purchase more later on.
Purchase farm goods from the shops in the cities scattered throughout the game. Before a Digimon can benefit from training at your farm, you must install farm goods that boost the stats you want to improve. To boost a Digimon's spirit level, you have three options: the book shelf, the study table and the pentagram. Their respective costs are 1,800 bits, 3,600 bits and 5,400 bits.
Leave your Digimon at the farm with the spirit-increasing farm goods installed. Each day, you get a farm report from Calumon, who tells you the stats of the Digimon that are training in your farm. You can retrieve your Digimon from the farm whenever you feel they are ready.
Equip your Digimon with armor, weapons and accessories that boost spirit. All of the Digimon weapons and armor, no matter what type of Digimon you have, boost spirit by 6 to 25 points, depending on the level of the equipment. For an added increase to spirit, equip your Digimon with a spirit ring, legend ring or ultima ring. These boost Spirit as much as 20 to 30 points.
