The Hosts Duplicitous

Enemy units within 3" of a HOSTS DUPLICITOUS unit with 10 or more models cannot retreat. In addition, once per battle, when a HOSTS DUPLICITOUS HORRORS OF TZEENTCH unit from you starting army is destroyed, you can roll a dice. On a 4+, add a HOSTS DUPLICITOUS HORRORS OF TZEENTCH unit with 5 models to your army. Set up the new unit wholly within 12" of a friendly HOSTS DUPLICITOUS HERO and more than 9" from all enemy units.
