Mistake on Page 121:
"Frantic Heroes are made by picking three Archetypes, and taking one Style from each."
Where is the mistake? That is correct.
Unless you mean how one of the Styles can be from outside your Archetypes, which is still true.
That's the one- when I first read through the book, I used that page for reference and missed the outside-archetype Style until it was pointed out to me elsewhere.
