In this game system, there is an important distinction between Skill Groups and Skills. While Skill Groups unlock a range of actions, Skills are more specific and the two tables are dependent on each other. It is also important to understand that the terms Physical Mental and Spiritual as they are used in this document are for organizational purposes only, there are no intended requisite attribute relationships. A player is free to use a physical skill and tie it to a Spiritual or Mental skill and vice versa.
