Wind Blast is a magic missile with a range of 24". The target is 'pushed' D3+1" directly away from the caster (it does not change facing). If the target unit comes into contact with impassable terrain it stops 1" away and suffers D6 Strength 3 hits. Treat the edge of the board as impassable terrain for the purposes of this spell. If the target unit comes into contact with another unit it stops 1" away and both units suffer D6 Strength 3 hits. Targets that cannot move are not pushed back at all, but still suffer D6 Strength 3 hits. The caster can choose to summon a more powerful wind that pushes the target back D6+2", rather than D3+1". If he does so, the casting value is increased to 14+.
