Also known as sith lightning.
A force power in which the user emits blasts of lightning from their fingertips. Only exhibited by the sith in the movies, don't know about the extended universe. Appears to be actually either low amperage due to the fact that it takes a hell of a long time to kill someone with it, or the jedi are capable of resisting its effects and a normal humanoid being would be killed instantly. Favored by the sith lords darth dooku and darth sideous. darths maul and vader did not exhibit this ability. Maul preferring his two ended dong extension and vader preferring the force choke.
darth sideous is so lame, he uses force lightning too much
