As with any true form of martial arts, there are many variants and adaptations. Some, such as the Lightsaber forms, require use of the Force. Others, such as Tam Beseri, require more academic knowledge such as in mathematics and geometry. Some are widespread, others are rare and known only by a few.
Each martial arts style works as a single Advanced skill that falls under Knowledge. Since they are Advanced skills, the practitioner must satisfy the prerequisite skill list along with any minimum dice level requirements before spending points on one of the forms.
To learn any of these forms, a character must have a teacher or a reliable medium ( such as a holocron ) that can demonstrate the moves and how the prerequisite skills come into play.
