A Custom Lightsaber is one constructed to reflect the personality of its owner.
Anyone can construct a custom lightsaber, however, a specially-modified lightsaber may only be carried by a Sith Warmaster, Obelisk Prelate, or Krath Archpriest . If you are this rank or higher the custom weapon will be displayed on your dossier after approval by the Herald.
The implementation and usage of dual sabers (two single lightsabers) is available to Sith Overlord, Obelisk Primarch, or Krath Pontifex.
The double-bladed lightsaber may only be carried by a Dark Side Adept or higher.
Custom lightsabers must be sent to the Herald for evaluation.
