All the weapons you need you will aquire thru side quests and mostly thru the "Legacy" Quests up to your 1st Generation Lightsaber then you will need to get resources to craft your lightsabers from then on. Your first lightsaber will be a training lightsaber at CL26. Added Note: do 10 missions from the mission terminal of your faction (Rebel or Imperial) for added EXP on a daily basis. May the Force Be With You.
