Khan Trick

 is a unarmed perk in Fallout: New Vegas.

Effects
Khan Trick is a special unarmed perk given to you for completing Aba Daba Honeymoon.

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 PC 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 PC 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).

Note

 * If you've killed Motor-Runner before you talk to Jack then you'll be unable to teach him new recipes therefore not being able to learn the Khan Trick.
 * 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

Bugs

 * 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. Tested on PS3 but requires confirmation.
