- Easy experience
Make sure your first three Digimon are higher than level 60 and you have three weak ones because your Digimon will grow a lot. Once you have reached Sunshine City and have gotten the Master ID in the 'Final Battle' mission, go through the portal. You will battle an OphanimonC. Overcome her to get 9,600 experience points. Save the game after the intermission sequence. The Chaos Brain is very confusing and has some powerful Digimon. Make sure to have revivers. Go through Chaos Brain, and you will see Grimmon with Chrono Core. Grimmon will soon digivolve into ChaosGrimmon. He will be at level 88. Your first three Digimon should all be Megas. Overcome him, and another intermission sequence will begin. ChaosGrimmon will digivolve into ExoGrimmon. He will be at level 99. Do not defeat ExoGrimmon if you want your Digimon to keep growing. If you decide to do this, your Digimon will lose friendship but will gain 15,000 experience points each time you do this. When you lose to ExoGrimmon, you will be at your house. From there, just repeat this trick as many times as desired.
