The lady was wielding a sword in hand and had two more swords flying around her. She was attacking and defending with the three swords.
The three swords meant that she had more avenues of attack than Goldwyn. Unfortunately, the two of them didn't have the same speed and power.
Goldwyn armament enhanced both his strength and speed, so even though he only had two arms to fight with, he was not at a disadvantage.
Actually, it wouldn't have mattered if he was slow and she could control four swords to fight with because she can't harm him no matter how much she hit him.
Whether it was striking Goldwyn's metal claws or his golden body, it always led to the creation of sparks. No matter how much she attacked him, nothing came out of it.
It truly felt as if his whole body was made of metal, which wasn't surprising to Arthur because the full release state of the Armament grants defense too.
