Using this technique, the user covers the ground and the area of the technique with a thick mane of snow, much akin to the passing of an avalanche. Any creature caught in the area of effect is pushed backward 1d4x5 feet and knocked prone. If the subject creatures are still in the area of effect after being pushed back, they are buried under 1d6x5 feet of snow and begin suffocating. To get out of the snow, a creature must succeed a Strength check (DC 20) in order to move 5 feet in any direction and stop suffocating once they exit the mass of snow.
A buried creature suffers 3d6 points of cold damage per minute until it exits the avalanche. This technique directly affects the ground it is cast on, and no fighting or movement will be possible atop of it until the snow is melted or moved away. Any structures caught in the line of effect of this technique suffer 2d4x10 point of damage. The effects of this technique dissipate and slowly fade away after 10 minutes.
Material Focus: A colossal (at least 5000³ feet) source of snow or ice nearby.
