Magus

During deployment, you can setup this unit in ambush instead of setting it up on the battlefield. If this unit is an INFANTRY or BIKER unit, you can set up this unit underground instead of setting it up on the battlefield or in ambush.

Each time a saving throw made for a <CULT> CHARACTER model from your army is failed, you can select one other friendly <CULT> or BROOD BROTHERS model with this ability within 3" of that CHARACTER model and take an Unquestioning Loyalty test. To do so, roll one D6, adding 1 to the result if that CHARACTER model is a PATRIARCH model: on a 4+, the test is passed and that CHARACTER model does not suffer damage. Instead, the friendly model you selected is destroyed and the attack sequence ends.
