Orbalisk armor

Orbalisk armor was a suit comprised of orbalisks, near-invincible parasites native to Dxun, that had a very hard shell, and were able to deflect even lightsabers. The parasitic creatures clung to the body using their thousands of tiny teeth, and fed off the dark side of the Force in the person.

The only people known to use orbalisk armor were Darth Bane and Freedon Nadd. Some of the orbalisks in Bane's armor were killed in a duel with five Jedi, and it was his own Force lightning that dealt the blow, after it was redirected on him by a dying Jedi master. Bane survived due to the healing techniques of Caleb, who had struck a deal with Bane's apprentice Darth Zannah.
