He’s a decent swordsman, but that is only about one percent of his real power, and most of those sword skills came from Diamante’s teachings and shit anyway. Law is also a martial artist on par with Lao G. Swordsman, devil fruit merchant, martial artist, surgeon of death, shockwave master… whatever box you try to put him in, he breaks out of it. In the end, he is an OP(e) god and a master of every style.
