Foxes are the only known species able to consciously harness and tap into the magic of the gods that is in the air and the earth. All other species have to be specially chosen to own magic, whereas foxes know how to take it and channel it into themselves, using it to achieve special powers.
There are many studies that foxes learn in order to harness certain powers. It usually takes a very long time, but some foxes with natural gifts may master them sooner.
Airchanging is not meant to be taught anymore, as major elemental studies - like Airchanging, Earthmoving, Firestarting and Waterbending - are incredibly dangerous when used. Airchanging is the art of manipulating the air. It is difficult and very, very draining, and takes about three years to master.
Deathbringer is the art of killing just by touching. It takes immense concentration to turn off and turn on, and takes about three years to master.
Earthmoving is the art of manipulating the earth. It includes stone and sand and takes about two to three years to master.
Farsight is the art of advancing your eyesight.
Unbreaking is the art of using magic to prevent injuries. It can be used to prevent any injuries, be they physical, mental or emotional, and takes about two to three years to master.
