Truthseeker (version 2)

All Lightsabers with the Serenity sound type have the same sound, including the Truthseeker (version 2). This isn't the official name, and this Lightsaber sound type may be labelled something like weaponmeleelightsaber07 in the background of the game.

I do not have a video of the Truthseeker (version 2), but you can watch a video of the Serenity's Unsealed Lightsaber weapon to hear the Serenity sound type, which is the same as the Truthseeker (version 2).

The Artifice crew skill trainer can teach players how to craft many crafted weapons sets as they level up in Artifice. However, these semi-retired crafted weapons sets are no longer available to be learned from the Artifice trainer from the launch of the game 1.0 - they were removed from the trainer in Update 4.0, and replaced with a more streamlined set of weapons schematics to be learned from the trainer. However, if you can find someone who learned the old schematics from the trainer pre-4.0, they can craft you these items, as the crafted items are Binds on Equip.
