I surrounded one of them with barrels and boxes and he did not know how to break out. I sneaked a character into the cavern who possessed a high teleport rating and managed to set up about 7 or 8 boxes or barrels which hemmed the knight against the wall. He did nothing to stop me or to go around while I was doing this. I ran out of boxes and time to deal with the second knight further on, but you get the idea...load up your party with empty boxes and barrels and have a ball while the death knights languish in their boxy prisons!
Edit: Yes, I know it is cheating, but so are "death knights."
