The first cyclops, which was hit by Arthur's Dark Magic, suddenly succumbed, not expecting to be weakened this fast. He fell on the ground and started wriggling before dying, at last.
This startled the four other parasites, including Claudia, who became more vigilant of Arthur's Dark Magic. It only took him one hit to eliminate one of them and this shows how deadly his magic is.
The remaining cyclops didn't last long either, after being struck by three slashes, it followed its comrade to the afterlife. Now, the two parasites guarding Claudia, their Queen, had to make a move.
However, she decided to join them to ensure their victory. Just like she proclaimed, Claudia was indeed a parasite and a stronger variant than the ones responsible for her safety.
