The Khan Trick is a special unarmed move that you can learn from Jack, who’s located in Red Rock Canyon.

Quick tips before you go learn the move:

• Bug-filled quest. The quest that you need to do to learn the Khan Trick is filled with bugs. This is not solved even when running the most updated versions of the game. Sometimes, certain dialogue options don’t trigger, NPCs become hostile for no reason and other quest-breaking bugs may render the Khan Trick impossible to get.
  • If this happens, you can use the “player.addperk 0015B8E7” (without the quotation marks). This will give you the Khan Trick perk and allow you to perform the attack as normal. Keep in mind that using console commands will disable achievements until you restart the game (though you can save after you’ve used the console command and restart the game).
• Science skill of 50 or more required. To learn the Khan trick, you’ll need to have a Science skill of 50 or more. This number can be temporary and boosted by Science boosting consumables/clothing (such as the Programmer’s Digest magazine or any of the scientist coats from the Old World Blues DLC)

Learning the Khan Trick

To learn the Khan Trick, head to Red Rock Canyon, located southeast of Jacobstown, and look for the drug lab, which is located in the back of the camp, on the other side of a narrow path between two hills.

Once there, you’ll see a blonde woman named Dianne. Talk to her and exhaust her dialogue options.

Eventually, she’ll mention that one of her couriers has gone missing. Agree to find him and head to Cottonwood Cove, a Legion slave camp located east of Camp Searchlight. 

Head up the road that leads in the direction of Camp Searchlight and look for a cross with a Great Khan named “Anders” crucified on it. Anders is the person you’re looking for. He’s also marked by a quest marker, so finding him shouldn’t be too difficult.

Once you find the courier, speak to him to confirm that it’s the correct courier and help him down from the cross. After that, return to Dianne. 

There is a chance that you won’t see the dialogue option to set him down from the cross, if this happens, simply exit the conversation and kill Anders. While you won’t get the full reward for finding him, you’ll at least be able to continue the quest.

When you return, Dianne will give you some caps if you saved Anders, then, she’ll ask you to deliver a package to a person named Don Hostetler.

He’s usually located at the Crimson Caravan, which is located just outside the two Freeside entrances. He will also be marked by a quest marker, which will make it easy to find him. It’s also possible that he will be in his home instead, in that case, go speak to him there. His home doesn’t have a map marker, but the quest marker will show you the way.

After you give the package to Don, go back to Dianne and she’ll reward you with some Great Khan reputation and 250 caps.

Note: Wearing a Great Khan Disguise is highly recommended for the next step.

Next, she’ll ask you to deliver a package to the fiends. Head to Vault 3, located inside the South Vegas Ruins.

Wearing a Great Khan disguise will allow you to slip inside without any combat. 

Head inside the vault and walk through the door at the back of the first room then turn right.

Next, follow the corridor and take the last door to your right. 

Now, take the stairs down.

Next, take the door at the back of the room and take a left.

Follow the corridor until you make it to a large, open room. Look for a hermetic door there and open it. Motor-Runner will be sitting inside.

Give Motor-Runner the drugs and go back the way you came and return to the drug lab at Red Rock Canyon and tell Dianne you delivered the drugs.

It is possible that Motor-Runner will become hostile or the dialogue option to give him the drugs won’t appear due to several different bugs associated with Motor-Runner. If this happens, you may attempt to attack him and holster your weapon. This has a small chance of fixing his dialogue, but it’s unlikely to work.

Return to Dianne and she’ll reward you and tell you that she doesn’t have any more work for you. Next, speak to the man in the drug lab, Jack.

You’ll need to teach him a couple of drug recipes. To do that, you need a Science skill of 50. If you have the required skill, you can pass the 3 Science checks in his dialogue tree, teaching him the drug recipes.

As a reward for your work, Jack will teach you the Khan Trick.

Effects of the Khan Trick

To execute the Khan Trick, move to the left or to the right and make a power attack with an unarmed weapon or your fists. When you do, your character will pick up sand/dust from the ground and throw it into the opponent’s face, which will temporarily stun them.

This attack only works on humans. Creatures like Deathclaws, Cazadores and mechanical enemies are unaffected by it.

Out of all of the special unarmed moves, the Khan Trick is by far the least useful. Rather than knock the opponents down to open them up to attacks (Like the Legion Assault or the Ranger Takedown do), it just makes them display the crippled leg animation which really doesn’t do anything helpful in combat.

Overall, this move is mostly for those who wish to get every perk in the game, rather than those who just want to have the best build. For the latter purpose, it’s better to save your time and skip getting this perk.
