This movie records the more difficult boss encounters of the instance, with the final one not shown because it's believed you have to defeat Prince Malchezaar to face him (Nightbane). The second two bosses we didn't put too many attempts in for the night because it was late and the next night our entire instance had reset. Hopefully the video doesn't spoil too much in the way of strategies, but I doubt it will.

Feel free to discuss the movie or Karazhan in general here:
