I was looking at the new hardcover Creature Guide and I couldn't find the rule for Henchmen I read in the original Tome of Adventure, plus it seems like none of the creatures are marked as Henchman. Did the concept of Henchmen go away in this iteration of the rules?

As I understand it the henchmen rule can be applied to all creatures, as the only thing you do is create a group of creatures (of equal size as the group of PC's) and lower their wounds to their To-value, only let them (as a group) attack once and let them add fortune dice depending on how large the henchmen group is. I think the rule still exist, but there are no specific henchmen noted in the lists, but I don't think there were ever specified henchmen.

It's in theGM'sGuide.

Found it - many thanks!
