Psy-Lance Bombardment

If a GREY KNIGHTS WARLORD from your
army is on the battlefield. Select one point on the battlefield and place a marker on that point. At
the start of your next Command phase, roll one
D6 for each unit within 6" of the centre of that marker, adding 1 if the unit being rolled for is
within 3" of the centre of the marker
and subtracting 1 if the unit being rolled for is a CHARACTER. On a 2-5, that unit suffers D3
mortal wounds, and on a 6+, that unit suffers D6 mortal wounds.
