You speaking nonsense, internal damage who didn´t work on Doffy doesn´t mean that his current attacks can´t one shot him.
Law legit became far stronger, has learn defensive and offensive power skills, his Countershock who also ignore durability,couldn´t even make Big mom bleed,couldn´t hurt her. And Countershock was the gamechanger for Law together with Gammaknife to kill Doffy.
Yet awakening did a seriously hurt and damage Big mom, who durability is hyped in similar league as Kaido.
And Kaido easily endure GK without much damage, Big mom seriously got hurt by awakening Law...
Current Law>>Dressrosa Law.
His awakening would one shot Doffy if he hit him again...
