In Digimon Survive, how do you get Deltamon? ...

Deltamon is one of the earliest Champion level Digimon you can recruit to your team, along with Fangmon, Meramon, and Dokugumon. Deltamon is useful because of its high attack value and excellent vertical movement score, making it excellent at securing high ground. The Triple Forces attack has also got some good upside, giving a chance to fire multiple attacks at the same time over long range an added critical advantage.

How to befriend Deltamon

The best ways to communicate with Deltamon is by negotiating with one during battle, like with any other wild Digimon. The first place youll be able to do this is during Part 3 of the story, outside the school.

Once you've answered all of the required questions, you'll be able to either ask for items or befriend Deltamon. There's a chance that befriending them will fail, but since this is a Free Battle area, you'll be able to return and try again as many times as you want.
