Telepathy / Legends Telepathy was the very basic ability to read minds or mentally communicate and project user ' s thoughts over small or vast distances with other individuals . Description . Every Force user , Jedi or Sith , was potentially able to use this ability . The range of telepathy itself is theoretically infinite , but the telepath must be able to sense the presences of those they wish to contact . Thus , communicating with non - Force - sensitives became nearly impossible over distances greater than a handful of kilometers , and the typical upper limit for Force - sensitives was approximately 1 , 000 kilometers . However , individuals who either shared a biological relationship or a particularly strong emotional bond were known to communicate across far greater ranges . In extreme cases ( such as the twin bond between Jacen and Jaina Solo ) , the link apparently had no spacial limit . The telepathy of most Force - sensitive individuals were not potent enough to truly read the thoughts of other beings , and could only sense the emotions or general mindset of those around them . This form of basic telepathy was more commonly known as Force empathy . While every Force - adept was able to use telepathy to some degree , very few of them were actually skilled enough to participate in actual telepathic conversations . Most Force - sensitive individuals could only exchange short four or five - word sentences to those that they shared close bonds with . Usually , Jedi employed telepathy only to read the states of minds or engage in silent communication . Eye contact , in part , allowed a user to have less difficulty in focusing on a target ' s thoughts . A very skilled user could create a telepathic shield to isolate their own brain waves , intercept stray thoughts , screen multiple minds simultaneously , whisper across space , yell without noise , keep secrets , and uncover the truths under layers of deceits and hidden memories . Adept pilots could even be able to seek information from other stars so as to navigate a starship through hyperspace without use of a nav computer . Moreover , telepathy also gave its user an advantage in combat , as it could be used to predict the next movement of an opponent , and furthermore to taunt and confuse opponents by echoing their voice in their head in every direction , masking the users position . Another telepathic abilities was to induce pain or project a telepathic blast to hurt the target ' s mind , as well as extract information for a persons mind cousing them extreme pain , also known as Mind Probe . Saesee Tiin , Plo Koon and Kit Fisto were three of the most skilled Jedi telepaths . Some species , such as the Iktotchi , the Anzati , the Hortek , the Quermians , Zeltrons , Umbarans , and the Draethos , had evolved a natural telepathic ability , common even to those of their number who could not touch the Force . When trained as Jedi , their natural talents were often magnified a thousandfold or more . This was the case with Saesee Tiin , whose natural prowess in the ability caused him great discomfort during his years as a Padawan . It was not until he was trained by Jedi Master Omo Bouri that he learned to better control his telepathic sense . Some Lamproids exhibited natural telepathy , although this was not a species - wide trait . As telepathy was a very basic use of the Force , the relatively untrained Luke Skywalker was able to employ it to reach out to his twin sister Leia Organa and call for her help during the Occupation of Bespin . Vader then ( as Luke and the group were escaping ) called out to Luke to again convince him to join him and embrace the dark side . The fact that the three were related allowed them to reach out over even greater distances . Beings who could use telepathy were banned from most casinos in the galaxy . Neural Storm was a telepathic ability that used psychic energy to overload a victim ' s neural network , causing extreme but momentary disorientation .
