Alter Damage was a Force technique used by the Jedi Order to change the damage their lightsaber inflicted upon a target.
Description
Mastery of this skill came hand-in-hand with mastery over lightsaber combat, as it was used in conjunction with use of the weapon. When used correctly, a practitioner could manipulate the energy of the lightsaber and reduce the damage caused to the target. Used while fighting both living and non-living opponents, this technique could make the difference between killing an opponent or completely disabling a droid or piece of machinery.[1]
