I'm try to add a witch hunter attachment to my deamon hunters. I just want a squad of arco-flagellants, but need a priest (cardinal Biggles). I am unable to figure out how to add the priest. I am using Army Builder 3.1 with the latest files. (Yes, I have all the codexes etc.) When I go to HQ priest is not an option. Could someone more skill with army buiolder help me out. Thanks
