I mean, sure, you can keep track of it like that, or the DM can keep notes that are more specific? I dunno. I feel like if you're doing that route, you may as well have a (hidden or not) likeability stat or friendship or mood or whatnot. Just my two cents.

Isn't that a lot for a Baby Digimon, most of which are gooey slimes?

I'm not sure Generation's required, because it does not increase with level, and you can play a game with no generation, only using the default Techniques and those that naturally transfer for each Digimon form. Or, at least, that's possible in the unmodified system. Also not sure if one Generation does anything? Plus I don't have any points left.

I'd rather there be communication before it comes to that, m'kay? Like, we're a team, right?
