World of Warcraft: Mists of Pandaria is the fourth expansion set for the massively multiplayer online role-playing game (MMORPG) World of Warcraft, following Cataclysm. It was announced on October 21, 2011, by Chris Metzen at BlizzCon 2011, and was released on September 25, 2012.
Mists of Pandaria raised the existing level cap from level 85 to 90. It introduced a new character class, the Monk, along with a new playable race, the Pandaren. The vanity pet system was overhauled and added a pet battle system. New PVE scenarios were introduced, and Challenge Modes were added for dungeons. The existing 41-point talent trees were replaced by a new system of tiered talents that are awarded every 15 levels. There are nine new dungeons, three new raids, and two new battlegrounds, such as the Temple of Kotmogu and The Silvershard Mines, as well as one new arena (The Tol'vir Proving Grounds).
The game is set after the events of Deathwing and the Cataclysm. The major setting is the titular land of Pandaria, one of the continents of the world of Azeroth. Discovery of Pandaria is made after a naval battle between the Horde and the Alliance. It had previously been hidden by magic since The Sundering, only to resurface.
