Use: Teaches you how to summon this companion.
This pet is awarded to players who compete in at least 50 games (3v3 matches) during the Qualification Round of the Arena Tournament. It is mailed to all current characters on the qualifying player's account. 200 games were required in 2009.
We've heard additional reports that an identical Murkimus the Gladiator was given out to the first wave of players who logged on in China after the new Chinese operator, NetEase, took over and reopened the WoW servers.
