Special Attack.
A unit with at least one model with Skinning Lash can make a Sweeping Attack against a single unengaged enemy unit when passing within 1″ (it does not need to and cannot move through or over that unit). The enemy unit suffers 1 hit with Strength 4 and Armour Penetration 0 for each model with Skinning Lash in the unit. A unit that loses one or more Health Points due to the Skinning Lash Sweeping Attack suffers -1 Discipline until the end of its next Player Turn.
