Instructions
Battle often with the Digimon you are trying to evolve. Any battle will do for raising Friendship. The more you battle, the greater your friendship with Digimon will become.
Avoid letting your Digimon lose in battles. Fight Digimon that are at or below your Digimon's level to avoid getting overpowered. Keep healing items handy when you are battling to raise your Friendship level. If your Digimon faints during a battle, its Friendship level will decrease.
Train your Digimon at the Digifarm with farm goods that increase Friendship. You can purchase farm goods at shops in every major city in "Digimon World: Dawn." The Keychain, Cell Phone and Digital Camera all boost Friendship and cost 1,500, 6,000 and 9,000 bits, respectively.
Visit the Digifarm and speak with your Digimon often. This works like speaking with any other Digimon in the game. The more often you go back to visit your Digimon, the higher its Friendship level will increase.
