Keep in Mind Needs
Tamers have it easy in Digimon World: Next Order since just about every action contributes EXP. Winning battles is one sure fire way to earn experience, but you don’t earn much early on, and you’ll have to fight way too much before finally making some headway. There’s also the act of completing objectives, whether they be side (blue exclamation points) or main (gold exclamation points).
However, you can rack up quite a bit on the side simply by attending to your partners’ needs in Digimon World: Next Order. As you play, your Digimon will grow hungry, tired, need to use the bathroom, become unruly, or seek praise. If you take care of these needs within a reasonable time you’ll actually earn experience (even if it doesn’t say so on your screen). Your Digimon’s progress and happiness directly contributes to your level as a Tamer. And increasing that level allows you to unlock skills that will make your time even easier.
