Hmm, when you say strength what do you mean lol?
A domain is an environment constructed with cursed energy and manifested through a cursed technique
It also gives you a buff in stats.
But when two domains clash the more refined one wins. It can also depend on compatibility and cursed energy.
Again what output lol?
I think overcoming a domain through sheer power is not possible lol.
Hmm I think he's got more than what was expected. I think that Kenjaku making him a vessel is the only thing. His father and grandfather don't look like sorcerers nor strong.
Again, as I said, if he inherits Malevolent Shrine it can be a battle I guess, if he can keep it up. Otherwise Megumi imo gets the dub there.
That's reserved for Gojo only.
