Units with a chill aura radiate cold into squares surrounding them. The ability value denotes the base size of the aura, which is increased by one by each level of water magic they have and by one for each point of cold scales, but decreased by heat scales. The aura inflicts 2 points of armor negating cold fatigue damage three times per turn to anyone in the affected squares. Cold resistance counts double against this damage because it is fatigue damage. Units with a resist cold(3) or greater are practically immune to the effects of Chill Aura.

The ability to quickly induce fatigue penalties during a protracted fight is very helpful.
