The Dwellers Below can be cast upon any unit of at least 5 models. It will not work on a smaller unit. Small hummocks appear in the ground surrounding the unit, and from each hummock a doorway opens and out pours a horde of tiny, shrivelled, brown-skinned creatures. They attempt to grab the target and pull it down into their burrows beneath the earth.

Every model in the unit must roll its Strength value or less on a D6 in order to resist the creatures' efforts. Mounted models can re-roll the dice if they fail. Any models failing to make their roll are dragged beneath the ground and do not reappear. As no wounds are inflicted no armour saves are allowed and any saves that would normally protect against or restore wounds are, of course, ineffective.
