Force opportunist

Opportunist was a Force skill akin to Force Focus that allowed practitioners to use the Force to expand their perception, putting them in a state where time seemed to slow around them to allow for the pinpoint timing of strikes with weaponry such as lightsabers, breaking through an opponent's defenses and opening them up for critical blows.
