In Jujutsu Kaisen, Domain Expansion is one of the most powerful techniques in the series. It’s a move that only a few characters can pull off, and when they do, it almost always changes the tide of battle. But if it's so strong, then why doesn’t every Sorcerer use it? That’s the big question fans often wonder about.

The truth is, even though Domain Expansion is a known ability in the world of Jujutsu Kaisen, it’s not something that just anyone can use. It takes insane skill, control, and Cursed Energy to even try. And even among powerful Sorcerers, many never learn it in their entire life. Let’s break down exactly why this technique is so rare and difficult to master.

What Is Domain Expansion?

Before we talk about why it's hard to use, let’s first understand what Domain Expansion actually is. In simple words, it’s a technique that creates a separate space where the user’s attacks are guaranteed to hit. Inside this Domain, their Cursed Technique becomes insanely powerful and accurate. The moment someone is trapped inside, they’re basically done for unless they have a way to counter it.

For example, Satoru Gojo’s Unlimited Void overwhelms the target’s brain with endless information, freezing them in place. Jogo’s Domain is a volcanic world that burns anything that steps in. Each Domain is custom-made for the user’s technique, which is why it’s so dangerous.

Why Can't Everyone Use Domain Expansion?

Now here comes the real problem: creating a Domain Expansion takes huge amounts of Cursed Energy and total control over one’s technique. It’s not something you can just learn in a few months or copy from someone else. Most Sorcerers can’t manage the energy or the mental focus needed to build a complete Domain.

Also, using Domain Expansion puts a lot of strain on the body. Even when someone like Megumi Fushiguro uses his incomplete Domain, it takes everything he has. A fully polished Domain like Gojo’s takes years of training and fighting experience. That’s why only top-level Sorcerers like Gojo, Sukuna, and a few elite Curse users have mastered it.

Risk Vs Reward

Another reason why not everyone uses Domain Expansion is that it’s risky. If someone tries to activate a Domain but fails, they leave themselves wide open to counterattacks. Worse, if their opponent also uses a stronger Domain Expansion, theirs gets overpowered and crushed instantly.

Think of it like this: using Domain Expansion is like pulling out your ultimate weapon. If you’re not ready or if your opponent is stronger, it could backfire badly. That’s why even skilled fighters like Nanami or Geto don’t use Domains; they stick to what they know they can control.

Final Verdict: It's A Rare And Deadly Art

In the world of Jujutsu Kaisen, Domain Expansion is like a final boss move. It’s rare, it’s deadly, and it’s only for the best of the best. The reason most characters don’t use it is simple: it’s too hard, too risky, and takes years of experience to even try. That’s what makes it so cool and exciting when someone finally uses it in battle.

So, when someone pulls off a Domain Expansion, you’re watching one of the most difficult and dangerous moves in the entire series. Not everyone can do it, and that’s what makes it so special.
