It can be acquired by completing the Aba Daba Honeymoon quest.
It is used by performing a power attack while moving left or right. This move throws dirt into the eyes of your enemy, temporarily stunning them. In third person view, the player character crouches down, and throws both hands forward and out, though no dirt or dust is visually displayed. In first person, the same animation takes place and you can see the player character reach down to the ground. While this animation causes the screen to move left and right, the throw will be in the place you were initially looking (or where it would be, based on aim movements during the animation).
- If the player character has killed Motor-Runner before they talk to Jack, then they will be unable to teach him new recipes and therefore not be able to learn the Khan Trick.
- This attack should only be attempted on humans, as it is completely useless on creatures.
- Due to numerous bugs with the associated quest itself, it may be difficult or outright impossible to earn this perk.
- Any effects that are applied on hit with an unarmed weapon will be used on an enemy if the dirt hits them. This is most noticeable with unarmed weapons that have visual effects on hit, such as displacer gloves and ballistic fists.
- If looking at the ground in first person, the camera will point even farther down, turning the camera upside down.
- The Khan Trick affects enemies wearing helmets, such as NCR Veteran Rangers.
- This is the only one of the four unarmed fighting perks that has (more or less) the same animations in first and third person.
- Characters and enemies that get hit by this attack will display a crippled animation.
It is possible, when doing this attack on The New Vegas Strip, the animation for the attack will happen but the attack itself may fail to do anything. [verified]
