The Carmine Assassin
Red light runs from the psyker's eyes, ears, nose and mouth, gathers around one model within 18", and closes on it. The victim rolls under its Toughness on 1D6 or dies outright, however many wounds it had, and no armour saving throw applies. A single crew member may be attacked this way; where the vehicle is enclosed, that crew member rolls two D6 and keeps the lower.
