Q: On page 87 of Mastering Iron Heroes, there are four bullet point describing the benefits gained by spending glory points. Points one, three, and four all are explained in the text, but bullet point two seems to have slipped through.

Was this accidentally left in, or was the explanation text left out?

Accidentally left in. The other abilities are all of equal use to all characters. Being able to spend glory points for tokens would advantage some character classes more than others.
