Players can now venture into Serpentshrine Cavern to confront Lady Vashj or ascend to The Eye of Tempest Keep to defeat Kael'thas Sunstrider in World of Warcraft: Burning Crusade Classic's first content update, Overlords of Outland.

While the update, which goes live today, makes it so the new raids are technically available, a lengthy attunement process is required to step into each instance. Players will need to have completed multiple other raids, lengthy quest chains, and heroic dungeons in order to actually get the ability to participate in Burning Crusade Classic's new content. The update also marks the start of a new Arena season, complete with new gear to earn, as well as introduces two new factions to earn reputation with in exchange for rewards.

Outside of new content, the update adds heavily anticipated features like guild banks. Prior to this point, guild leaders would often make multiple level one characters and use their bag space and bank storage to hold the guild's various crafting materials and supplies. That process became cumbersome quickly, with those operating the guild banks needing to log out of their main character, log in with a bank character (or several), and coordinate materials between them all. Guild banks simplify this process greatly, letting members deposit and withdraw items with ease.
