A mighty shadow bull rushes away from the caster in a straight line up to 18" long. Any model the bull touches suffers 1 S4 hit causing 1 wound. Any unit that sustains casualties must take a Panic test.
Although expressed in rather colourful terms this spell is basically comparable to a cannon shot and to other spells with short ranged projectile effects such as Gaze of Mork. Characters with units can therefore benefit from the 'Look Out Sir' rule as they can from cannons and other weapons and spells which affect models beneath a line or which utilise templates.
