The Armory is a searchable database of information for World of Warcraft. Since the Armory pulls its data from the actual game servers, it is the most comprehensive database on the characters, arena teams, and guilds of World of Warcraft in existence.While the Armory data gets automatically updated, it is not a quite suitable replacement for traditional, non-"life" character databases. This is because it only saves a character's status after their last logout, so there is no way to display multiple sets of gear (for instance healing, PvP, or resistance sets) or the effects of different talent builds.When the Armory first came up, many players were concerned that their items and stats were viewable for all to see.
