WOW Power Leveling: The EXP granted upon completion varies depending on how many are gathered
There is another Party Quest, also for level 51-70, available in some versions. It is called the Ludibrium Maze Party Quest. It can be started from the main town center of Ludibrium, and consists of wondering WOW Power Leveling through a maze of many rooms, trying to gather as many tickets as possible.
The EXP granted upon completion varies depending on how many are gathered. Like Henesys PQ, there is no boss.
Another party quest for characters level 50 and above is the Zakum Party Quest. There are three major parts to this quest.
The first involves a party of any number of members entering a quest which requires the party to collect certain items, with several obstacles. The second is a two-part horizontal jump quest. It is quite difficult for a first timer, but as you progress, you will gradually get the hang of it.
There is a minor quest in between the second and third, which requires you to hunt for 30 Zombie's Gold Tooths to forge the item required to summon Zakum. The third and final part of the quest is fighting Zakum itself.
However, in some versions it is being abused, and higher level players demand payment from lower levels to enter the Altar for the helm specially.
