The next Midnight update closes out the Quel'Thalas and Zul'Aman storyline. The new campaign, The Promise of Tomorrow, leads to The Unbinding of Kith'ix: a single-boss raid against an ancient C'Thraxxi general the Amani sealed underground, with Lady Liadrin fighting at your side. It comes in Story, Normal, Heroic and Mythic, and Mythic uses a flexible group of 15 to 25 players.

For anyone who wants more than Delves, the Labyrinth of Kindo'jan opens: an old Amani funeral complex with nine chambers and Valeera Sanguinar as your companion. You can clear it in one session or one wing at a time, and rewards go up to Mythic gear, plus cosmetics and titles. There is also a Tier 11 solo challenge.

In Eversong and Zul'Aman, an Aqir Invasion starts for ten minutes every hour: a chain of public events that ends with a boss, built from six scenario types and eight affixes such as swarms of small aqir or webweavers that cocoon players.

The power boost comes later. Orin Straylight finishes his research during maintenance the week of October 20, and only then do Ascendant Venomstones start dropping from Heroic and Mythic raid bosses, +10 and higher keystones and Tier 11 Bountiful Delves. Ten of them push a maxed-out Season 2 weapon, trinket or necklace to a higher item level. The crest cap lifts that same week.

You can prepare now. Pick up In the Catalyst's Shadow from Decimus in Voidstorm, then Prismatic Potential from Orin Straylight in Silvermoon City. Turn both in before maintenance the week of October 6, and Orin will sell you one extra Nebulous Voidcore a week for gold, Voidlight Marl or Veteran Mistcrests.

The patch goes live on October 13 in the Americas and on October 14 in Europe, each with weekly maintenance.
