Hailstorm is a direct damage spell. Place the small round template anywhere within 24" – it then scatters D6". All models underneath the template suffer a Strength 4 Hit. The Wizard can choose to increase the power of the spell to use the large template rather than the small template. If they do so, the casting value is increased to 13+, the template scatters 2D6" rather than D6", and the spell causes Multiple Wounds (D6).
