Shearing, or more correctly, Force Shearing, was a unique Force ability used primarily by Jedi Knight Bryn Fulcron. It consisted mainly of using the Force to project many ethereal versions of oneself around the area of combat, hopefully confusing the enemy as to which one is real. The technique was especially useful versus those who did not feel the call of the Force, although quicker-witted ones could still probably spot the true user. It consumed a significant amount of energy, and could not be used rapidly in succession. The trick to it was personal memories of combat, which would account for the individual illusions differing moves and appearance.
