So, I had an accident a long time ago while trying to do a spell. As a result, my temperature is hypothermically low, although it does not cause problems, and I have developed a resistance to the extreme cold-a need for it almost. For as soon as I am out of a subzero environment, I start to feel unwell. At first just a bit of fatigue, a little lightheadedness. But as the temperature climbs, it gets worse. On the rare occasion I have been in an environment above 40 degrees (celsius) I collapse unconscious. A few more degrees would be fatal. So, is there a spell which I can use to be more resistant to heat? Because it kind of sucks being uncomfortable and in poor health three out of four seasons in the year.
