Remains in play. This spell has a range of 24". Each model (including characters) in the unit's front rank suffers one automatic Strength 4 hit.

As long as the spell is in play, if the target unit moves for any reason, every model in the unit suffers a further Strength 4 hit, and then the spell is automatically dispelled.

If cast on units with a 360° line of sight, such as skirmishers, the Wall of Fire does not form and the spell has the same effect as a Fireball.
