Faction Change service The Faction Change service is a paid service being offered by Blizzard since September 2nd , 2009 in the US and September 17th , 2009 in the EU , which allows you to change the faction ( Alliance or Horde ) of a character . This service is being offered in response to player requests . This service has been designed carefully to avoid disruption of the current gameplay on the realm , so certain restrictions will apply . The current cost is $ 30 ( USD ) , €25 ( Euros ) or £20 ( Pounds ) per character to switch . The change is permanent , however , after a cooldown period , you can purchase an additional change to go back to the player ' s original faction . The initial release was only available to US players , but was also made available 2 weeks later for EU servers . Notes . At this time , all achievements and quest lines related to the Argent Tournament and Shadow Vault are reset after using the Faction Change service . Reputations . When a character changes factions , their home city reputation level translates into the same level of the home city of their new opposite faction race . For example , a Gnome turning into a Blood Elf would see his Gnomeregan Exiles reputation become his new Silvermoon City reputation . Then , reputation with the default counterpart of the new race converts into the counterpart of the original race . Using the previous example , since the default counterpart of Blood Elf is Draenei and the default counterpart of Gnomes is Tauren , the gnome ' s Exodar reputation would become the new blood elf ' s Thunder Bluff rep . Reputations with the remaining home cities will then convert to their opposite - faction counterparts according to the default pairs . Mounts . As Patch 6 . 2 . 4 ( ) , only faction - specific PvP mounts will convert to their opposing faction equivalents . Prior to Patch 6 . 2 . 4 . When a character changed factions , the mounts associated with their original race automatically converted into those of their new opposite faction race . For example , a Troll turning into a Night Elf would see his Raptor s turn into Nightsaber s . As Patch 6 . 2 . 4 ( ) , this was limited to only faction - specific PvP mounts . Then , the mounts associated with the default counterpart of the new race converted into those of the counterpart of the original race . Using the previous example , since the default counterpart of Night Elves are Undead and the default counterpart of Trolls are Dwarves , the Undead ' s Skeletal Horse s would become the new dwarven rams . The mounts associated with the remaining home cities will then convert to those of their opposite - faction counterparts according to the default pairs . Other Mounts . The following mounts would always convert to a default opposite - faction counterpart . As Patch 6 . 2 . 4 ( ) , this was limited to only faction - specific PvP mounts . Achievements . Faction - specific achievements include several in the Player - vs - Player category ( such as those to defeat the racial leaders and enemy players in their capital cities ) , and are included in certain world events like Midsummer Fire Festival and Hallow ' s End . The majority of these achievements follow a 1 - to - 1 conversion to an opposite - faction equivalent . The achievements relating to the Argent Tournament , including becoming a champion for each home city , will not translate in a faction change . Spells . Spells that are affected by a faction change include mage portals , racial spells ( which are simply replaced by those of your new race ) , and a Shaman ' s Bloodlust / Heroism . Items . Some items will automatically convert into the corresponding items of the opposite faction . These items include Insignias of the Alliance / Horde , and PvP weapons and armor such as the ( which will turn into the , and vice versa ) . If an item has an opposite - faction counterpart , that information will be displayed on those items ' information page as displayed by the Armory . No items will be lost during the faction change process . Other . Quests . All currently active quests will be removed from the character ' s quest log . Faction - specific quests will be removed from the character ' s completed quest list , as well as any faction - neutral quest that is part of a quest chain . Standalone faction - neutral quests will remain in the character ' s completed quest list . The opposite - faction version of a faction - specific questline is available in its entirety after a faction change . Flight Paths . The number of flight points that a character has unlocked is set to certain thresholds based on the character ' s level , in 10 - level increments . For example , a level 70 character may have all Azeroth and Outland flight points unlocked , but none in Northrend . Hearthstone . After a faction change , a character ' s hearthstone is automatically set to the inn inside the capital city of their new race , which is also where they re - enter the game world as a member of the opposite faction .
