This spell affects all Orc, Goblin and Snotling units of any type (including Black Orcs, Night Goblins, etc) on the table, provided they could charge the enemy if it was their Movement phase. Pump Wagons are assumed to have a charge move of 12" and a 360° charge arc for this purpose. Affected units will immediately attempt to charge the enemy (whether you want them to or not!). Roll 2D6" for each unit and move it towards the foe. If there is a choice of targets move the unit towards the closest. Any units which move into contact with the enemy count as charging. The enemy are caught by the suddenness of the advance and can only hold they can't stand & shoot, flee, etc. Note that if the enemy cause fear or terror the charge is treated as pursuit into fresh enemy.
