Dun Möch

Dun Möch was a form of lightsaber combat that was used in conjunction with a lightsaber

The Sith aimed to completely dominate an opponent's spirit through whatever means possible by employing their own lightsaber combat doctrine. Dun möch commonly involved spoken taunts, jeers, and jests that exposed the opponent's hidden, inner weaknesses and/or doubts. Other variations on dun möch involved usage of the Force to throw large, weighty objects at the Sith's opponent during combat, which both distracts the opponent from the battle and could potentially cause damage. Darth Vader uses this against Luke Skywalker in their duel on Bespin's Cloud City. Count Dooku and Darth Sidious also used this form against Yoda in their respective duels with the Jedi Master.
