Force lightning was a well known Force ability, most often used by practitioners of the dark side of the Force, especially the Sith. Because of this association, the ability was commonly referred to as Sith lightning.
Force lightning could be used as the Wracking Energy, restricting target's movement.
Force Shock was a Force power that allowed the user to create an energy spark that would track and damage the nearest enemy. The shock could be thrown at an opponent to stun and injure them, or could be set loose to track an opponent until it dissipates. The shock would not last more than five seconds or so before disappearing into a tiny burst of heat, but it was a useful technique for Sith apprentices.
Force Storm
Force Storm was a Force lightning variant. The user would raise his palm upward and would create, through the Force, an explosion of electrical energy directed at all foes in the vicinity. It was used by both the Sith and Dark Jedi during the Jedi Civil War. It also appeared as a tornado of energy which created a great disturbance in the Force. Jedi could also join together to create a Force storm, though its use was frowned upon by more orthodox Jedi.
Unlike the Force lightning, Force Storm was not limited to attacking enemies in one direction, as it affected all foes within a certain radius from the user. Revan and the Jedi Exile may have mastered this particular power. Darth Bane and Darth Sidious were also notable users of this power; Bane being able to call upon a nearly uncontrollable Force Storm shortly after having been taught the basics of Force Lightning by Githany, who herself had only learnt the power the same day from Qordis.
Chain Lightning
Chain Lightning was a variation of Force lightning with the difference being that the lightning was able to strike one person and then move to another or several others. As it was more powerful than the standard lightning, it required a greater amount of discipline and concentration to project and sustain the stream of lightning.
these powers, if used with caution and correctly can be used to keep ur enemy still without hurting him
