- Did you mean the bear form attack Maul, or the weapon ?
The Maul is a large pit located outside the three instance wings of Dire Maul in the middle of the Broken Commons. Like Gurubashi Arena in Stranglethorn Vale, entering the Maul flags players for PVA and allows them to attack and kill other players in the Maul, regardless of faction. When a party is in the Maul, however, you cannot attack members of your party.
Sometimes the Maul will be empty, but sometimes there will be an opponent inside for brave gladiators to face: either The Razza, Skarr the Unbreakable or Mushgog. When there is something in the Maul, an NPC named Griniblix the Spectator will enthusiastically yell that it has arrived. He can be heard by anybody inside any part of Dire Maul.
On occasion, herbs can be found in The Maul, including Black Lotus.
Players can enter the Maul either by simply dropping into it or by entering a doorway on the west side of the commons that takes them into a tunnel leading past packs of sleeping Gordok hyenas and finally to the fighting area. The tunnel is the only exit from the Maul. It may be most prudent to enter through the tunnel, since dropping down causes the player to take damage from falling and their opponent may attack them before they have recovered their health.
