  The caster causes the air around themself to warm (or cool) to a comfortable temperature. This effect occurs immediately but only lingers a natural length of time. For example, if the area around you is subject to a stiff breeze, the warmth that you’ve created will probably be blown away in a matter of seconds. On the other hand, if you cast it within a tent, it might last longer—but if it’s really cold outside, it might still cool down inside within 20 or 30 minutes. Obviously, this weave is most effective when cast in an enclosed, insulated space. The casting level of this weave varies according to how uncomfortable the temperature is to begin with.
