So if you arent a jedi or sith you must roll like everyone else to find what you seek. The force calls out toward the Jedi, and Sith can hear them. It should also be known that Troopers, mandalorians, all officer classes can use crystals to power up their guns, but like everyone else they will need to be found. They can feel people dying, just as they can feel the heat of the battle. This is a Lightsaber crystal guide, most force users can use them, but Jedi mainly get called by the crystal, for the crystal and the blade become an extention to a Jedi's willpower.
