Ice Flowers

Transmutation [Cold]
Creates a mound of solid ice covered by a layer of soil which bursts violently through the surface, flinging dangerous ice shards and small stones throughout the area, turning the surface of the ground into dense rubble. The shards and stones deal 1d6 points of damage per caster level (maximum 15d6). Half the damage is cold damage.
