Sith Conjurer

Sith Conjurers were Sith Sorcerers who became more proficient with dark side magic and were able to preform more advanced spells and techniques. They were somewhat common in the first several Sith Empires, and their field was greatly expanded by Sith Lord Naga Sadow, who himself learned from the ancient sorcerer and Dark Lord of the Sith named Cluj. By the time of the Clone Wars, they were extinct. Conjurers rose again under Palpatine in service of the Galactic Empire, and continued to exist even at the time of Darth Krayt.
