Ki focus (A ki focus is an implement that certain classes use as a focus for their inner magical energy, known as their ki. A ki focus might take the form of a training manual, a scroll of ancient secrets, or a blunt training weapon. To use a ki focus, you must first attune yourself to it. Some characters study their ki focus to attune themselves to it. Others meditate with it or wield it as they practice their fighting techniques. Once you have attuned yourself to a ki focus, you must either wear or hold it to use it as an implement.
