How do you Digivolve on Digimon Battle while not in a Battle?

You can't Digivolve your Digimon in Digimon Battle outside of battles. Digivolution in Digimon Battle is battle-exclusive, meaning you can only evolve your Digimon during battles.

Here's how it works:

1. Gain Experience: Your Digimon gains experience points (EXP) from battling other Digimon.

2. Reach Level Up Threshold: Once your Digimon accumulates enough EXP, it will level up.

3. Digivolution Trigger: Certain levels (and sometimes specific battle conditions) will trigger a Digivolution sequence.

4. Choose Digivolution: You'll have the option to choose which Digivolution path to take.

Therefore, you can't actively choose to Digivolve your Digimon outside of battles. You need to fight and gain EXP to reach the levels and conditions necessary for Digivolution.

If you're looking to Digivolve your Digimon in Digimon Battle, make sure to participate in battles regularly!
