This spell requires at least two Halfmen to cast, and usually involves 5 or 6 (each of which casts the spell). As each casts the spell a wall of lightning springs up between each pair of Halfmen (up to a maximum distance of 10 Legats). Anything living passing through this wall suffers D4+8 damage ignoring armour. As the Halfmen move the wall moves with them and is often used to heard their prey into a tight space. The wall remains in force for 5 minutes + 1 minute per Halfman in the wall.
