Today, Blizzard announced on its WoW blog that Patch 4.2 is ready and available on public testing realms. The 4.2 content update will feature a new raid, backdropped in the Firelands:
World of Warcraft patch 4.2 will offer hardy adventurers an opportunity to turn the tide in the Firelands, a huge outdoor raid of the highest difficulty, with 10-person and 25-person normal and Heroic modes. It will be a scorching opportunity to delve into this Elemental Plane, where six unique bosses stand between you and the reinvigorated Ragnaros.
4.2 will also feature a new epic quest and two areas with new dailies:
Patch 4.2 introduces an epic quest that will challenge those daring enough to complete the legendary staff Dragonwrath, Tarecgosa’s Rest. The great staff duplicates destructive magics, and also bestows upon its wielder the ability to transform into a member of the Blue Dragonflight. Those who complete the staff won’t be the only ones to receive a reward, though. As this task requires the dedication of an entire guild, upon completion of the staff all guild members will receive a unique non-combat pet to call their own.
And if you want to hear all the details, you can tune in to Blizzcast, where Game Director Tom Chilton provides a complete breakdown of the content, new gear, and updates to classes.
