Dun Möch Dun Möch was a form of combat that used distraction and doubt , usually through taunting , in conjunction with lightsaber combat . 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 or doubts , which had the end result of eroding the opponent ' s will . Mental attacks would also be utilized during combat in order to strip one ' s concentration with the Force , making an opponent less precise and effective . Such a thing could be quite deadly , especially against Jedi , since concentration was of vital importance when using the Force . As such , Dun Möch embodied using the Force as a form of psychological warfare . Usage . Correctly executing Dun Möch required great patience , a rare trait of the Sith during the time of the Brotherhood of Darkness . This need for patience was exhibited by Darth Bane during his duel with the Zabrak Sirak during a combat training session at the Sith academy on Korriban . He exhibited patience by drawing out the battle and demoralized his opponent by withholding the final blow and capitalizing on his mistakes . Instead he allowed the tantalizing closeness of Sirak ' s defeat fuel his vengeance before unleashing it with a strong enough blow to disarm him and end the duel . Lightsaber combat instructor and Blademaster Kas ' im commended Bane ' s use of Dun Möch and declared it a valuable lesson to all of the other students at the conclusion of the fight . The most successful practitioners of Dun Möch were the ones that took the practice to the level of plotting . Desann used Dun Möch by faking the death of Jan Ors and taunting Kyle Katarn about his powerlessness , tricking the enraged Katarn to reveal the location of the Valley of the Jedi . Darth Traya lied to Colonel Tobin ( who was working for Darth Nihilus at the time ) about a supposed Jedi Academy on Telos IV . Nihilus took the bait , which left him vulnerable to Meetra Surik , who killed him . Darth Sidious , arguably the greatest practitioner , would plan events that would take years , if not decades , to come to fruition . The Clone Wars could be considered an extreme usage of Dun Möch by Sidious , in order to distract the Jedi Order to allow him to wipe them all out quickly with Order 66 . Aside from this , he also used a rather extreme version of Dun Möch during his duel with Yoda in the Senate , where he proceeded to hurl several repulsorpods at Yoda , constantly forcing Yoda to dodge until Yoda turned the tables on him by redirecting a repulsorpod back at him , forcing Sidious to dodge . However , a common misconception is that Dun Möch was only used by Sith . Like Force lightning , Dun Möch could also be employed by Jedi in certain circumstances . It is theorized by some that this may have occurred during the confrontation between Darth Sion and Meetra Surik on Malachor V , though this use did not match the standard usage of Dun Möch and was completely different from any seen before . Sion was indestructible by conventional methods , as he was capable of healing his wounds in an instant . Surik instead used taunts and arguments to erode Sion ' s will , which in the end caused Sion to sacrifice his own life to the Force . However , most applications of the technique by Jedi had the more benign goal of motivating opponents to surrender , as shown by Obi - Wan Kenobi ' s taunts of Asajj Ventress during their duel on Teth , though again , this may not have actually been Dun Möch . Notable examples . Darth Tyranus used Dun Möch on Geonosis , taunting Obi - Wan Kenobi , Anakin Skywalker , and Yoda respectively . Tyranus would later focus this skill on Anakin during their rematch onboard the " Invisible Hand " , but before that , he used this skill to taunt Anakin of his fear of pain and loss . Darth Sidious also used this form against Yoda in his duel against the Grand Master , both by taunting Yoda verbally and displaying his mastery of telekinesis in an " unnecessary " flashy fashion . Luminara Unduli used this in her duel with Asajj Ventress , mentioning to Ventress that her fighting style appeared to be a sloppy version of Darth Tyranus ' Makashi form , though she suffered from the boomerang effect . Darth Maul also used this in his second duel against Obi - Wan Kenobi , by cruelly reminding the Jedi Master how Maul killed Qui - Gon Jinn in front of him , to a great effect . He later applied this against Judd during the Battle of Moorjhone , forcing the Jedi Master to choose between facing the Sith Lord and saving the Moorjhoni from certain destruction . This gave Maul enough time to rescue his brother , Savage Opress . Galen Marek employed this technique against Darth Vader during their duel , taunting him concerning his inability to break free from the Emperor ' s control while Marek himself had broken free of Vader ' s . These taunts enraged the already frustrated Vader , causing him to redouble his attack against Marek and ultimately to waste a great deal of energy , tipping the duel in Marek ' s favor . During the Assault on Kamino , Vader used Dun Möch against Starkiller , an imperfect clone of Galen Marek , telling him to overcome his artificial feelings for Juno Eclipse . Though enraged and possessed with the desire for revenge , the clone stayed his hand and reluctantly spared his creator ' s life . Vader , in 0 BBY would use it against Obi - Wan Kenobi on the Death Star , but , as shown by Kenobi ' s calm retorts , he experienced little success . He used it again facing Luke Skywalker in their duel on Bespin ' s Cloud City to great effect . Vader applied the technique again during their duel on the second Death Star ; however this usage proved counter - productive , as Skywalker was spurred into a rage instead of being demoralized by the taunting . Kyle Katarn was repeatedly exposed to Dun Möch during the Valley of the Jedi crisis against the Seven Dark Jedi . During Katarn ' s duel with Boc Aseca , the Twi ' lek never ceased laughing and taunting with gibes such as " You ' re an angry one , aren ' t you ? " and " Feisty ! " , combining them with his evasive jumping technique to frustrate Katarn into making a mistake . After their respective defeats , both Maw and Jerec attempted to goad Katarn into turning to the dark side by striking them down . Maw , in a sense , succeeded . By the time Katarn faced Jerec , however , his emerging maturity in the light side caused him to react uniquely to the Dun Möch : Katarn neither struck Jerec down nor spared him ; instead , he rearmed the murderous Dark Jedi so as to kill him in honorable combat . Desann ' s Reborn warriors utilized Dun Möch to frustrate the members of the New Jedi Order that they encountered in combat . Kyle Katarn , once again exposed to Dun Möch , managed to ignore their taunts and emerge victorious in every duel he had with the Reborn . The New Reborn of Tavion Axmis ' s Sith cult carried on this tradition and were often heard taunting Jedi with expressions like " Do you fear me ? " and " I thought Jedi were powerful . " Jacen Solo applied Dun Möch when he used the Force to hurl dislodged bricks at Mara Jade Skywalker during their brawl on Kavan . When that proved useless in stopping Mara ' s advance , Jacen used a clever variation of Dun Möch by disguising his own face as his cousin ' s with the Force to manipulate Mara Jade Skywalker ' s love for her son against her . The result was Mara hesitating during the fight and Jacen mercilessly striking Mara down . Jacen ' s own sister Jaina employed Dun Möch against her brother in his new guise of Darth Caedus , Dark Lord of the Sith . While dueling Caedus in the bowels of his personal Star Destroyer , the " Anakin Solo " , Jaina used the Force to hurl bodies , gurneys , and other items at Caedus , in an attempt to halt his advance . Luke Skywalker used Dun Möch in the same battle by disguising Jaina as himself . Over one hundred years later , Cade Skywalker used Dun Möch against Darth Krayt during their duel , taunting him about his Yuuzhan Vong " armor " that was slowly killing him . Boomerang effect . If not carefully applied , Dun Möch could backfire upon the user , spurring the intended target to anger instead of overwhelming him / her with fear . During a sparring match , Exar Kun tried to make Sylvar lose focus by claiming the superiority of Humans over Cathar , only to have her lash out at him with her claws . Krath leader Satal Keto heavily taunted the Jedi Ulic Qel - Droma during their duel , so much so that Ulic succumbed to his anger and struck Keto down in a fit of rage . Darth Tyranus was victimized by this twice , both times when he was engaging Anakin Skywalker . The first instance took place during their duel on Tatooine , which Tyranus had spent taunting Skywalker , culminating in him displaying a hologram of Skywalker ' s then - Padawan Ahsoka Tano being ambushed by three of Dooku ' s IG - 100 MagnaGuards . The second instance took place during their duel on the " Invisible Hand " , when Dooku taunted Anakin about his fear and his refusal to use his hate and anger . Both instances prompted Anakin to viciously attack Dooku , ultimately defeating him . However , Dooku was spared in the first incident . Luminara Unduli also became a victim of this when she taunted Asajj Ventress , calling her lightsaber style " unrefined " , " amateurish " , and " sloppy " . This angered Ventress , who pressed the attack . With the aid of a blast of hot steam from a nearby vent , Ventress temporarily damaged one of Unduli ' s eyes , and looked likely to win the encounter . Only the intervention of Ahsoka Tano swung the balance of the encounter in favor of the Jedi . Anakin Skywalker was later the victim of this effect when , as Darth Vader , he attempted to taunt his son Luke on the second Death Star , only to send Luke into a fit of anger . The same happened to Maw who , injured , taunted Kyle Katarn with false and exaggerated details of his father ' s death . This resulted in Kyle giving in to anger and striking down the unarmed Dark Jedi . The Sith Saber , Gavar Khai taunted Ben Skywalker when they dueled . However , it had the opposite effect on the young Jedi , calming him which gave him the edge in the duel . In some cases , spurring an otherwise passive target to anger was the desired effect , as opposed to failed usage . Darth Sidious often employed this against potential apprentices such as Darth Maul , Anakin Skywalker , and Luke Skywalker , in order to make them give into their inner darkness and therefore make them easier to convert to the dark side of the Force . Desann ' s unorthodox application also relied on this , as he needed Kyle Katarn to be angry enough to seek out the Valley of the Jedi to regain his Force powers quickly , thus revealing the Valley ' s location . Inverse Dun Möch . In addition , Luke Skywalker used the very opposite of Dun Möch aboard the second Death Star . The young Jedi attempted to turn Darth Vader to the light by reminding him that there was still good left in him and that he was still capable of love . Luke was successful and Anakin Skywalker ultimately redeemed himself . Around 4 , 000 years earlier , this method may have been used by Revan on the Star Forge to redeem Bastila Shan , and later Revan attempted to redeem his former apprentice much in the same way . Even earlier still , Jedi Knight Cay Qel - Droma may have used this method in an attempt to sunder his brother , Ulic , from the throes of the Krath . By using his brotherly love , Cay sought to penetrate the darkness surrounding Ulic and bring him back into the light . His attempts were in vain , however , for Ulic only gave in to his anger and murdered Cay in cold blood . Only in death were Cay ' s urges successful ; upon seeing his brother ' s murdered corpse , Ulic renounced the dark side and started down the path to redemption .
