As two actions, a hail of rock-hard ice pounds to the ground in a cylinder centered on a point within 100 meters. Each creature in the cylinder must make a Reflex saving throw. A creature takes 2d8 bludgeoning damage and 2d8 cold damage on a failed save, or half as much damage on a successful one.
Hailstones turn the storm’s area of effect into difficult terrain until the end of your next turn.
You can increase the bludgeoning damage by 1d8 for each additional mana expended.
