You imbue a mass of fallen snow with mobility and a semblance of life. The snow to be animated may be natural or magically created (as with the sleet storm spell). Snow animated by this spell is treated as an animated object. You can animate 1d3+2 Large animated objects, 1d3 Huge animated objects, or one Gargantuan animated object (see the Monster Manual entry for animated objects for statistics). The animated snow can assume any basic shape you wish, and it attacks as directed by your vocal commands. Animated snow possesses the Blind and Trample special attacks as detailed on page 18 of the Monster Manual for animated objects. In addition, they have the cold subtype, and do an additional 1d6 points of cold damage on a successful hit.

Animated snow objects suffer 1d6 points of damage each round if they exist in a place with temperatures above freezing.
