THE HAND OF GORK CASTS ON 9+
You may cut this on one Orc or Goblin unit (of any type) within 24", provided that the target unit could charge the enemy if it was the greenskin's Movement phase. If successfully cast, the unit will attempt to charge - move the unit 21)6" towards the enemy. If there is a choice of targets, move the unit towards the closest. Any unit that moves into contact with an enemy unit counts as charging in the usual way. The enemy are aught by the suddenness of the advance and can only hold before greenskins charging with the Hand of Gork - 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' (see page 76 of the Warhammer rulebook).
