Body Magic is a type of Magic in which users convert magical energy into the creation or destruction of energy in their own body. The end result is they can become faster, stronger, have more endurance, or are more durable, depending on the application.
A more advanced technique is changing shape, but to change the shape of one’s body takes years and must be done very carefully.
Regeneration is impossible unless the biomass is provided to regenerate missing parts. However, a skilled magical healer may be able to reattach a severed limb over many laborious hours.
