Wrath of God

{9}{6}"
Choose a point within range on the table and place a counter there. At the end of each subsequent Magic Phase roll a D6; if 1-3 is rolled, add another counter on the same spot. If 4-6 is rolled, each unit within (2D6+X)", where X is equal to the number of counters, suffers 2D6 hits with Strength 5, Armour Penetration 2, and Magical Attacks. The spell then ends, remove all counters.
