Slip into the Turbulent Timeways

news.blizzard.com:

Once more, the Bronze Dragonflight has discovered growing disturbances in the timeways, with several rapidly intersecting our own!

Beginning the week of September 26, Timewalk through a previous expansion each week for five consecutive weeks. This grand tour through World of Warcraft’s past will start with Cataclysm and end with Wrath of the Lich King.

Also, for a limited time, the Timewalking quest in Valdrakken from Kazra will offer an increased reward—a Heroic level Cache of Vault Treasures with items level 428-437. The reward upgrade is only available for this special Timewalking event. After Turbulent Timewalking has run its course, the reward returns to ilvl 415 Cache of Vault Treasures.

Here’s the expansion timeline for Turbulent Timeways:

Gather your staunchest allies and head into the Firelands raid dungeon to take on the elemental lord Ragnaros and his cohorts—and take on six dungeons from Deathwing’s era— during Cataclysm Timewalking.

When: The Firelands raid is available throughout the Cataclysm Timewalking event.
Difficulty: The difficulty is set to Normal and, like any Normal level raid, will not be available through Raid Finder.
Minimum Level: Players level 35 and above are eligible to participate.
Bosses: (7) Beth’tilac, Lord Rhyolith, Alysrazor, Shannox, Baleroc, the Gatekeeper, Majordomo Staghelm, Ragnaros

During Cataclysm Timewalking, you can assemble a raid group of between 1 and 30 players to step into the molten domain of Ragnaros. Don’t have a regular group? The Group Finder (I) can help. Create your own group in the Premade Groups section or search for like-minded adventurers.
