Description
The temperature in the area rapidly cools so cold that even Hell itself would freeze over. The temperature is reduced to -50° F at which deals 1d6 points of lethal damage per minute (no save). In addition, a character must make a Fortitude save (DC 15, +1 per previous check) or take 1d4 points of nonlethal damage.
A character who takes any damage from cold or exposure is beset by frostbite or hypothermia (treat them as fatigued). These penalties end when the character recovers the nonlethal damage they took from the cold and exposure.
In addition a dense ice storm forms and any external area is filled with flying ice that deals 5d8 damage to exposed creatures, objects and structures. Half of this damage is cold damage while the other half is treated as piercing, slashing, and bludgeoning. This ice also obscures all sight, including darkvision, beyond 5 feet. A creature within 5 feet has concealment (attacks have a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker can't use sight to locate the target).
Water also rapidly freezes to a depth of 1 foot for each round it is exposed.
