[Star Wars] Are there any Sith that prefer to use other weapons over a light saber?
gpt
Well, Lumiya was trained by Darth Vader, and was known as the Dark Lady of the Sith.  However, whether she counts as a "true" Sith Lord is a matter of debate.  In any case, Lumiya favored a lightwhip, which was similar to a lightsaber, except the "blade" part was long and flexible, instead of simply being a straight, rigid shaft of glowing plasma.  

Lumiya was not the only wielder of a lightwhip, as she found the schematics for it in an ancient Sith tome.  Therefore, it is likely that there were some earlier Sith who also used lightwhips.
