Defeating The Undead Knight - Champions of norrath.

This guy has a fast attack speed and can easily stun lock because of it. I recommend stocking up on healing potions and maybe even a cold/fire enchant on your weapon if you have one. But more importantly, use your stun/root abilities if you have them. I would use shield bash in this video, but I didn't have a shield equipped. It's tough getting the first hit in, but once you do, you can get multiple in a row.
