Rod Of Ice

This rod looks like a long sliver of ice and is cold to the touch, but deals no cold damage to its wielder. The wearer can use the rod to make a melee touch attack that deals 1d4 points of cold damage to any creature struck. Also, once per day on command, the wielder can touch the rod to the ground to create a 30-foot cone of ice that encrusts the earth, affecting the area as per the spell grease.
