Kapitel 1833: Monopolize Or Rush Forward.

Golden Light was just too powerful, and it required just a glancing blow to damage the target with the full might of the Authority using it. So it is normal for his to have the highest speed at killing. The second highest couldn't come close to him at all. 

Legion-2 was the second fastest at killing the skeletons. He had 7,000 divinity in Strength and could deal ((7,000 x 2) +1,000) with Myriad Armament for a total of 15,000 in a single attack.

He could attack as fast as 6 times in a second so even though he could kill any skeleton in a single blow too, he couldn't do it as fast as Legion-3 and he needed to crush the target with his club to truly put them down. So he could only managed 6 kills per second.
