I came up with something for the stealthy kind of char.. Sith Assasin? :ph34r:
Anyway, a single npc stands guard in front of a chest, door, wathever. The assassin sneaks up behind him, puts his/her lightsaber (shut off) against the back of the npc, and turns it on, and the blade pierces the guard silently for high/extreme damage... How 'bout that?
