Ah, I understand. Thanks for the clarification~

I don't even wanna be that dude's successor anyways, he was a butt.

Oh, one more thing I was wondering: How does one know one's affinity? Do you understand it innately, or is it a trial and error thing? Is there a test for it?

This was asked a little while ago too, so I'll just copy/paste my answer from before.

[quote=@Feyblue]Probably something of the sort that's revealed through a ritual or an oracle of some sort around the time they're like 10 or so. Likely, children below at least that age can't use magic very well, and their affinities may be shifting and unstable. Plus, y'know, using magic is taxing so it could damage their health if they pushed it too early.

Basically, think of it like one of those handwaves in crummy isekai where you go touch a magic ball and it tells you what your level is/what cheat power you have/whatever. Gives a list of elemental affinities that you're compatible with, and then it's up to you to cultivate those through practice, or you lose them.

Usually, you'd expect just about everybody to get their magic tested as kids -- even commoners -- since it's something just about everybody has and even if you're not gonna become a super mage, it still determines what sorts of things you can do for your own daily convenience.
