Located at the main gates of Orgrimmar, High Overlord Saurfang is the brother of the veteran orc Broxigar and one of the most powerful NPCs in the game. He hits a full plate warrior around 10-12k normal hits, up to 15k crushing blows and up to 19k critical hits. Besides Intercept Stun and Mortal Strike, he has an ability called Saurfang's Rage, which triggers whenever Saurfang is struck by a critical hit, dealing instant 10-12k physical damage to the enemy who dealt the crit, literally meaning instant death for nearly all the classes. Entire armies have fallen before Saurfang himself, even without any enemy Horde players interfering and Orgrimmar raids usually come from the back gates just because of him. By far, no one was able to kill him, but his difficulty is far superior than any end-game raid boss because of his ability to one shot the critical damage dealers and the insane amount of damage he deals, even without crits or crushing blow.
