Ki
Ki is the energy of life. Often equated with the soul, the effect of Ki on people is usually rather subtle. However, all living things have ki. Martial artists can harness their ki to do amazing things, and in this roleplay, those heights are so profound that proper training can practically make a demigod out of a man.
Ki amplifies the all around physical characteristics of a person, from strength, to speed, to durability, without the requirement of having incredibly huge muscles, making them very adaptable and robust combatants. Ki fighters, as they're called, can also launch bursts of their own life force on command, called ki blasts and ki streams. They can also sense other bodies of ki in their vicinity, and even use their ki to fly at incredible speeds. In emergencies, they can cause their aura of ki to explode about them, making for effective air brakes and pushing away objects that come too close for comfort.
Characters who possess supernormal Ki powers cannot also have a Physical power level.
