to a character's class (e.g., warriors can be alchemists, mages can be skinners, etc.). However, some skills available to certain classes (e.g., the ability to track animals) are useful to certain professions. Characters can also learn all secondary professions: cooking, fishing, first aid and archaeology. In the Burning Crusade expansion, additional profession specialisations were added, allowing a character to gain new restricted techniques such as an alchemist mastering potions, elixirs, or transmutations. In the Cataclysm expansion, the secondary profession of archaeology was added which allows players to dig up and recover artifacts from all over the game. As well as banding together to form groups, players can also band together to form a guild. These organizations allow players several benefits, such as easier communication through a shared chat channel and an identifying guild name and tabard.

Guilds can also make use of an in-game calendar, allowing guild members to view scheduled events, and respond to them with whether they can attend or not. This calendar can also be accessed without need to log into the game, using the Armory feature. Guild members that accomplish goals together gain guild experience and advance the level of their guild, granting guild members various benefits.

World of Warcraft takes place in a 3D-representation of the Warcraft universe that players can interact with through their characters. The game features five continents on the world of Azeroth, as well as the realm of Outland that was added in the expansion The Burning Crusade. Warlords Of Draenor introduced the realm of Draenor, an altered past of Outland. The second expansion, Wrath of the Lich
