Force Adepts were Force-wielders of all species with varying powers and abilities. Some of these Force Adepts were known to wield Force weapons such as quarterstaffs imbued with the Force, which were able to withstand and inflicted more damage than a lightsaber strike. Often they were with little to no formal Jedi training in the Force and often coming from primitive planets.
The second group of Force adepts is the concept used for a class in the Star Wars Roleplaying Game Revised Core Rulebook. In Saga Edition the Force adept would be turned into a prestige class with specific rules (such as item imbuing), while an official guide for converting between editions suggested the scout class for the "primitive" variety of Force adepts.
