New dungeons, dual talent specializations, user interface improvements, and much more arrive today with The Secrets of Ulduar, patch 3.1 for World of Warcraft.

Though it snags top billing, the massive dungeon of Ulduar is just the tip of the iceberg in patch 3.1. The patch sees the implementation of a relatively expensive but extremely convenient dual specialization system, allowing players to change their role on the fly. Fury warriors become protection warriors; frost mages become fire mages; and overpowered warlocks become even more overpowered warlocks with the click of a button.

The Argent Tournament in Sindragosa's Fall challenges players to triumph in various tests of skill in order to win the favor of the Argent Crusade. An improved quest tracking system is finally put in place. Ground mounts can swim!

For a full list of changes, check out the official patch 3.1 preview on the World of Warcraft website. For an extremely overdramatic trailer featuring several Warcraft superstars, press play below.
