play on. Each realm is in one of four different categories, depending on which set of combat rules it uses. These can be either where players are mainly focused on defeating monsters and completing quests, and player versus player combat is not permitted unless inside opposing cities, (player versus environment or PVE), or where open combat between players is permitted (player versus player or PvP). There are also dedicated roleplay (or RP) versions of both these types, where players are encouraged to control their character as if they were an inhabitant of a fantasy world. Realms are also categorised by the language players are encouraged to use, offering in-game support in that language. Players are able to transfer their established characters between realms in the same territory (North America, Europe, etc.) for a fee. As of patch 8.1.5, a player may create a maximum number of fifty characters per account on any realm. Once a player has selected a realm, an option to create a character is available. A player can select one of two opposing factions to place their character in: the Horde or the Alliance. Characters can only communicate and group with other characters of the same faction. Each faction has seven (including the Pandaren, that are neutral at the beginning) races to choose from. Race determines the character's appearance, starting location, and initial skill set, called "racial traits". The Alliance currently consists of humans, night elves, dwarves, gnomes, draenei and worgen; the Horde currently consists of orcs, tauren, Forsaken, trolls, blood elves and goblins. The draenei and blood elves were added as part of the Burning Crusade expansion. Worgen and goblins were added for the Alliance and Horde respectively in the following expansion pack, Cataclysm. In Mists of Pandaria, the pandaren were added as World of Warcraft's first ever "neutral" race. At the conclusion of the beginner zone quests for pandaren (around level 12), the player must choose to permanently join either the Alliance or the Horde. As of Battle for Azeroth there are ten additional allied races for players to use, which are generally variants of existing races with unique racials and themes. Further options to customize the appearance, such as hairstyles, skin tones, etc. are also available. Once set, the face and skin tone are not able to be changed; however the hair style, color, and other decorations, such as earrings and facial hair, can
