Way of Void or Kukan-do was a Mastery 7 mystical void kiho that was considered by many to be a dangerous practice. It allowed the monk to fill their chi with the vast expanse of the void, then project it into an opponent. This locked the spirits of the monk and the opponent in a deadly embrace which must be maintained using eye contact. If successful, neither the monk nor target might use any kiho, spells, or tattoos until the kiho ceased. The kiho lasted until the monk released it or the monk lose consciousness.
