Ice storm

Ice storm is an evocation spell that blasts an area with hail.

Effect
Great hailstones pound down, dealing 5d6 points of damage to creatures in their path; the damage is 3d6 impact plus 2d6 cold.

Arcane Material Components
A pinch of dust and a few drops of water. (Oddly enough, this is essentially the composition of snow, which occurs when water freezes around an airborne particle.)
