Just as the abilities Force cloak and Force stealth function, a spell of concealment, achieved through the use of Sith magic, gave the spellcaster the power to obscure or conceal the existence of either a single person or a group of people. The Dark Lord of the Sith Darth Zannah employed this spell to approach undetected and impale the Echani weapons Jedi Master Raskta Lsu. Furthermore, she utilized it to render both her Master Darth Bane and herself invisible while they were concealed within a clandestine subterranean chamber located in Caleb's residence. When paired with the insanity spell, this tactic deceived the Jedi, leading them to mistakenly believe that her relative Darovit was the final remaining Sith Lord.
