Waves of darkness

When performed by an individual adept in Sith sorcery, waves of darkness was a dark-side Force power conjured through Sith magic that created palpable waves of darkness—often visibly literal in their obscurity and accompanied by roaring, thunderous sounds. When exposed to waves of darkness, beings suffered from feelings of intense despair and confusion before feeling compelled, if detained under the spell's power long enough, to flee the scene of the disturbance.

In 4000 BBY, the technique was used by sorceress-Queen Amanoa against the Beast Riders and their Beast-Lord Oron Kira during the final battle of the planet Onderon's Beast Wars. A later practitioner, Sith Lord Darth Tyranus, used the power against Jedi Knight Obi-Wan Kenobi and his Padawan, Anakin Skywalker, in 23 BBY.
