Ice Storm
Heavy snow and sleet rain down during an ice storm, obscuring vision and dealing damage. Great hailstones pound down dealing 2d4 points of bludgeoning damage and 1d6 points of cold damage to every creature in the area. For each minute that a creature spends in the storm, they take a further 1d4 point of bludgeoning damage and 1d4 point of cold damage. Creatures inside this area take a -4 penalty on Perception skill checks and the entire area is treated as difficult terrain.
