Ah, thank you. Yeah, that guide is nearly identical to the one in the core set rulebook. I wish there was a little more in the way of how to do powers for your homemade character, like suggested powers or ways to incorporate pre-existing powers of other characters onto your character. For instance, if I wanted to make a wizard, I could take a list of all the wizard character powers currently in the game and then use that as my list of potential powers to give my made-up wizard character. I'm just trying to avoid making up my own powers, I guess, because there's no good way to know they're not too powerful without the playtesting that I don't want to go through :P
Anyways, thanks for the answer! I've been a big fan of this game for a long time, and I'm excited to try out the core set when I get the group together again!
