Prescient Brethren

Malediction: If manifested, select one enemy unit within 12" of this Psyker. Until the start of your next Psychic phase, each time that enemy unit makes a Normal Move, Advances, Falls Back, or makes a charge move, roll one D6: on a 4-5 that enemy unit suffers D3 mortal wounds; on a 6, that enemy unit suffers 3 mortal wounds. A unit can only be selected for this psychic power once per phase.
