Some individuals attuned to the Force could amplify the Force abilities of others who had a less potent link to the Force. Palpatine, after his resurrection, executed dark side ceremonies to strengthen his Dark Side Elite, events that generated a disturbance perceptible throughout the galaxy.

Nevertheless, the texts acquired by Darth Sidious from his own master indicated the potential to elevate the Midi-chlorian levels within living organisms through Force manipulation.
