The coolest thing about Jim Darkmagic - to me, and something that comes up in the book where Jim and Omin meet - is that he thinks of himself as a performer first and a wizard second. Likes: Adoring Crowds. Dislikes: Books and Scrolls. And underneath that is the revelation that he thinks close-up magic and card tricks and shit are way harder and way cooler than yoking the raw power of the universe. In the storied, interdimensional manse of the Darkmagic wizarding family, Magic - like Baseball - is just something your dad is always making you do.
Now, it is true that after the Wish which rolled back fifteen years to the very origins of Acquisitions Incorporated, we were given the option of changing something about our characters in addition to having seven hard-earned levels stolen from us. I feel like Omin has plenty of baggage and was fine as is. Certainty has made a few changes we don't really know as a party yet, and Evelyn's shift to an Oath of Redemption paladin is a super cool take on her character. Mike has some ideas also, but they're what I would call "Mike Ideas."
