Sacrificial Dagger

Each time this model attempts to manifest a
psychic power from the Malefic discipline,
if it is within 3" of any friendly
INFANTRY units (excluding DAEMON and
CULTISTS units), you can select one of those
units and make a sacrifice. If you do so, the
selected unit suffers D3 mortal wounds and you
can add 2 to the psychic test taken for that
psychic power.
