Inescapable Judgement (Psychic)

Grey Knights model only.  Each time an enemy unit within Engagement Range of the bearer's unit Falls Back, the bearer can use this Enhancement. If it does, roll one D6: on a 2-5, that enemy unit suffers D3 mortal wounds; on a 6, that enemy unit suffers D3+3 mortal wounds. These mortal wounds are Psychic Attacks.
