be changed by visiting barbershops within capital cities. The entire appearance of a character (including face, skin tone, gender) can be changed via Blizzard's paid character re-customization service - however, this changed in the Shadowlands expansion which completely removed the paid re-costumization service and incorporates it into the barbershops for free. Depending on the race chosen and the expansions installed, a player then has five to eight of the game's thirteen character classes to choose from. The mechanics of each class vary, with some geared towards melee combat, while others are more suited to attacking from range or casting spells. The game has three roles, DPS (damage dealer), tank and healer; a member of any class can be customized for the DPS role, while members of some classes, known as hybrids, can also be customized as healers, tanks or any of the three roles. Currently available classes are: druids, death knight, demon hunters, hunters, mages, monks, paladins, priests, rogues, shamans, warlocks and warriors. Originally, paladins were available only to Alliance races and shamans were only available to Horde races, but both classes were made available to both sides in The Burning Crusade. The death knight, introduced in Wrath of the Lich King, is a hero class, with the characters beginning at level 55 (roughly mid-way to a maximum level), already equipped with powerful gear. Creation of a death knight required the player to already have at least one level 55 character on their account, since Legion this is no longer the case. The demon hunter, introduced in Legion, is another hero class that requires the player to have a level 70 character. Once a player has one, the player is permitted to create a demon hunter that starts at level 98. While a character can be played on its own, players can also group up with others in order to tackle more challenging content. In this way, character classes are used in specific roles within a group. Players are also able to customize their character through the use of talents, which are further abilities related to their character class. Characters are also able to learn two primary professions from ten options. These can be gathering professions, such as mining, herbalism or animal skinning. Characters can also choose from gear crafting professions, such as blacksmithing or leatherworking, or item enhancement professions such as enchanting or jewelcrafting.
