Prerequisites: Cold immunity.
Benefit: You radiate intense cold in a 10-foot-radius, dealing 1d6 points of cold damage per round to all creatures within the radius. The cold is so severe that mundane protections (such as multiple layers of heavy clothing) are ineffectual against it. Only cold resistance or cold immunity prevents this damage.
