Digimon Survive: How to Digivolve

gamerant.com:

Much like the Pokemon series to which it is so often compared, Digimon features its own form of evolution. Digivolution allows Digimon to transform into brand-new forms, often increasing their power levels by huge amounts in the process. Unsurprisingly, perhaps, Digimon Survive also features this mechanic, though it's a little different than it is in some of the earlier Digimon games.

Digimon Survive: How Long to Beat

There are two ways to Digivolve a Digimon in Digimon Survive, neither of which are available to players right from the get-go. However, as they play through the main story, they'll gradually gain access to more and more powerful forms. Some of these are obtained through the use of special evolution items, while others are acquired in the heat of battle thanks to the strong bond that's shared between the Digimon and its human.

How exactly a Digimon evolves will depend on the type of Digimon that players are using. Agumon, Falcomon, Labramon, and the rest of the Digimon who automatically befriend the party will Digivolve as part of the main story, with players then able to select their Digivolved forms in battle for a set amount of SP. When it comes to Agumon, exactly which forms are unlocked will depend on the choices that players make as they play, with the player's Karma affecting the Digimon's evolution path.

Digimon befriended during Free Battles are a little different to main party Digimon, in that they'll instead require the use of items in order to Digivolve. They won't return to their base forms after evolving either, so players will need to think carefully about how best to use their evolution items. This is also true of Guilmon, who players will be able to download if they purchase Digimon Survive
