Electrical fellow had decided to ignore Overlord as well, boy, these assassins were really starting to get on his nerves. Incompetence is one thing, but being rude and ignoring the target for the sake of your pride is just hurtful. With a flick of his wrist he threw the remaining ash from his incindiary target off his hand and to the ground, what a pity, he had hoped to use the blood from his foes to create some mud. But at this point, three foes died and no blood was spilled. Save for a sheen of blood that now coated his sword, but that wouldn't be significant enough for mud arts. 

Damn shame, really. One fellow's death was swift and brutal, and that fellow had ignored him in just the same way as sparky here. Too bad. 

Putting both hands on his weapon again, he withdrew the tip of his blade from the dirt and raised it upwards. Aligning the sword with his eyes, allowing him to see just past it to Arthur. "Well, good fellow. Rest in peace." Those words were muttered, very likely to be heard by Greystroke, but still barely above a whisper. Overlord twisted himself and placed the blade in prime thrusting position just below his left arm. The blade turned parallel to the ground and the undead began a charge towards Arthur. 

Though it would take a moment to actually reach Arthur, Overlord didn't opt to make the mistake of letting out a primal roar at him. The only noises that his electric target would hear would be the clattering of his armor against his bones, which is admittedly a noticeable sound. 

This charge would result in a Overlord's blade being thrust through Arthur's back and out of his chest, spearing him on his blade and followed by a grizzly twist. Should it land, of course.
