Vitakineticism is an Adept discipline, wherein the user heals people by extracting negative energy from their person. But although this process heals the the patient, it drains the user of some energy. Vitakineticism also has offensive capabilities, as shown by Doctor Melior in Resurrection. When he was using it to attack Skulduggery Pleasant, his face turned red and he started steaming then. Red light burst from his body, attacking everybody in his vicinity.
It is implied that Kenspeckle, Brennock and Reverie all used it, as they are all seen healing people with their bare hands in several occasions. However this is unconfirmed.
