DOOM

While this shadow rests upon the enemy's soul, death
seeks them out above all others, each blow or shot that
comes their way rendered inescapably lethal.
If manifested, select one enemy unit within 18".
Each time a Core or Character unit from your
army makes an attack that targets that enemy unit,
you can re-roll the wound roll. If the result of the Psychic test was 10 or more, you can select one
enemy unit within 24".
