A character using this spell causes an assault of stones to burst upon any individual or group of enemies within 48 yards. This is a magic missile attack, causing damage like missile weapons. Target restrictions apply in the same way as for normal missile fire.
An Assault Of Stones automatically hits its target, causing D6 Wounds at S 4. If cast at a group, it will hit 2D6 individuals. Victims may not make a Magic test , but armour protects as normal. The stones have a 50% chance of hitting either the head or chest.
