Law got hit with the same attack that broke most of Zoro's bones, but he kept fighting Big Mom with unlimited energy and now he can still get up to try to fight Kaido
Some magical medicine was introduced straight out of nowhere just to put Zoro back into the battlefield, he learned ACOC in the middle of battle without training, just another ass pull power up for Zoro
All in all, I think Law has more Luffy level plot armor, because we saw him get folded by Doflamingo two weeks ago and get turned into a damsel in distress, now he has awakening, Yonkos level endurance, and the voice of all things in just two weeks
