Domain Expansions are considered to be the most powerful technique in any sorcerer's repertoire and are even referred to as the apex of Jujutsu sorcery. Jujutsu Kaisen has shown many different versions of this powerful technique, mostly belonging to the most powerful characters in the series. Despite this, Gojo's Unlimited Void is a step above even other Domain Expansions and is the strongest one next to Sukuna's Malevolent Shrine.
