So I wanna play Kroak as a part of Dracothion's tail army. In the rules it says that the named hero does not get a command ability. The Dracothion's tail rules state that the slann general must take an ancient knowledge trait. Does that mean that I dont get any benefits from this allegiance if I want kroak to be a general? Also is it worth to play kroak and not just slann since you loose such a good trait?
