            desc: Winter's Wind kicks a blast of ice and wind around the wearer.  It causes
              everything within 10 ft of them to be difficult terrain, while
              also providing resistance to cold damage.  It does cause fire
              spells to have greater effect, providing vulnerability to fire
              damage at the same time to the wearer.
