As two actions, a hail of rock-hard ice pounds to the ground in a cylinder centered on a point within 90 meters. Each creature in the cylinder must make a Reflex saving throw. A creature takes 3d6 bludgeoning damage and 3d6 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 and cold damage by 1d6 for each additional mana or psi expended.
