chapter 7 missing hero rules?

Looking for rules on how to stat an independent or supporting hero in D@W. Earlier in the book, it is commented that rules will be presented for them in chapter 7…

Should I treat them like a unit? 50-1 HP and, damage?

Does a supporting hero only contribute morale and spells?

Heroes are the last thing in Chapter 8 in my (admittedly outdated) copy.
