Low Level Quest Rewards Legacy Of The Sith Weapons

These low-level weapons sets are awarded for specific quests on specific planets, and you can only get them while playing a specific story / Combat Style. Most of them are a part of your class story quests - if you skipped the class story, or played the wrong role or class when the mission completed, there's no way to go back and get that specific weapon, though there may be look-alikes out there.
