Norfeller was facing that exact situation now. Although five Death Knights were besieging Norfeller, none of them were his match at all. However, the perfect cooperation between the five Death Knights made his speed almost useless. They were greatly restricting his movements, and even though he was moving from left to right like a black ray of lightning, he was still like a bug trapped in a transparent jar which could never break through the invisible walls.
The attacks that Norfeller launched were all blocked by the Death Knights, and Norfeller's figure also appeared in between the Death Knights. There was a tinge of panic on his sullen face, and even though he was well aware that he wouldn't be able to share much of his master's burden with his current abilities, since the enemy was too overpowering, he still didn't mind risking his life to grasp even the slightest opportunity for his master.
