So those unique race kids almost all do that… get a slightly more advance version of the human basic classes but… having them in the party can mean you get a chance to get another. I hear rumor that some events might even advance them AND the higher class is available for purchase.
I won’t ruin the surprise but one of the most awesome characters I’ve run into that you can’t purchase comes one of those kids you selected, but I am not sure how it’s triggered. I just know I chose Chance a couple of times and… got it. Chance is, well hugely risky.
I just don’t understand how those two can wind up so far apart it takes us 20-30 rounds to meet up and the best they can do in a challenge is to summon a low level pig that won’t even make it to round two!
