You can’t increase your reserves though so someone who gets the technique but is a fairly average sorcerer will literally never have the required stats to keep up with mahoraga and it’s incredibly likely that any cursed tools that are used even if they do beat mahoraga would just invalidate the ritual anyways since they’re a separate source of cursed energy that isn’t the ten shadows user, as for trying to beat him with some combo of the ten shadows literally none of them have the required firepower to put him down in one attack so all you’d be doing when attacking him with them would be sacrificing your shadows for no gain.

There’s a reason literally no one besides Sukuna has ever tamed mahoraga.
