Download World of Warcraft: Wrath of the Lich King 3.3.5a Client

World of Warcraft: Wrath of the Lich King (WotLK, 2008) took players to Northrend to face the Lich King and added the Death Knight, the first hero class. Version 3.3.5a (build 12340) is the final patch of the expansion and the one most WotLK private servers run on. If a server's launcher asks you to install WoW version 3.3.5a (12340), this is the client you need.
