Leia employs a gravity-altering device to amplify the weight of a Rigellian assassin. Devices that disrupt gravitational fields were frequently encountered and readily available in numerous commercial establishments. Merchants and transporters often utilized them to manipulate the gravitational forces acting upon a designated item for a limited duration. The specialized field generated by these disruptors could be configured to facilitate the effortless movement of substantial cargo. Furthermore, these devices possessed the capability to be adapted for inverse functionality, resulting in a rapid and significant augmentation of an object's weight.
Princess Leia Organa leveraged such an instrument to elevate the mass of Darth Vader's porter to the seventh power of its original value, which caused him to descend rapidly into a large hole created by his own immense weight.
