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.
Snow animated by this spell is treated as an animated object.
You can animate four Large animated objects, two Huge animated objects, or one Gargantuan animated object.
For details, see the Animated Object entry, page 13 of the Monster Manual.
The animated snow can assume any basic shape you wish, and it attacks as directed by your vocal commands.
Animated snow objects possess the Blind and Trample special attacks as detailed in the Monster Manual entry 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 take 1d6 points of damage each round if they exist in a place with temperatures above freezing.
