A unit with this special rule may perform a 'Spectral Reapers' attack against a single enemy unit that is not engaged in combat. To do so, this unit must move (by flying) over the unit it wishes to attack during the Remaining Moves sub-phase. Once this unit's movement is complete, the enemy unit suffers a single Strength 4 hit, with no armour save permitted (Ward and Regeneration saves can be attempted as normal), and with the Flaming Attacks and Magical Attacks special rules, for each model in this unit that moved over it.
