Honestly I don't exactly care for info on skills he can buy only the ones he actually has. There is no real benefit to knowing possibilities that will never come to be.
its to show the character is thinking. The choice ability is just as much about character development as it is about power. additionally because this character is more op then your average character, it forces the author to keep raising the bar on creative challenges and and writing ability to describe those challenges. Brave author, much respect. it nice to see a character who is overpowered and still thinks about tactics over raw power.
