Hailstorm 2014

Balls of ice slam to the ground in a 20-foot radius, 40-foot high cylinder centered on a point within range for the duration. The balls of ice turn the storm’s area of effect into difficult terrain. Any creature starting its turn in the cylinder must make a Dexterity saving throw. It takes 5d4 bludgeoning damage and 5d4 cold damage on a failed save, or half as much damage on a successful one.

When you cast this spell using a spell slot of 5th level or higher, the bludgeoning and cold damage both increase by 1d4 for each slot level above 4th. Additionally, the radius and height increase by 5 feet for each slot level above 4th.
