1. The Season 3 Dungeon Pool

Midnight Season 3, launching with patch 12.2 Eclipse this winter, brings eight dungeons into the Mythic+ rotation. Per Blizzard Watch's September 14 coverage, the pool mixes one new dungeon with seven returning favorites spanning BfA through Cataclysm.

Dungeon	Expansion	Notes
Thraegar's Stand	New (Patch 12.2)	Three-boss dungeon; Thraegar Earthen lore
Magister's Terrace	Burning Crusade	Redesigned form, dangerous trash pulls at higher keys
Maisara Caverns	Midnight (returning)	Routing optimizations from earlier season
The Underrot	Battle for Azeroth	Frequent Mythic+ visitor, five seasons total
Iron Docks	Warlords of Draenor	Popular for large pulls and path choices
Sanguine Depths	Shadowlands	Infamous gauntlet and hard-hitting bosses
The Stonecore	Cataclysm	First Cataclysm dungeon in Mythic+, Ozruk challenge
Uldaman: Legacy of Tyr	Dragonflight	High Tyrannical boss HP pool challenge

Blizzard Watch notes the pool has "a lot of actual caves, which feels appropriate for a patch about delving into the deepest levels of the planet." The Stonecore's inclusion is notable as the first Cataclysm-era dungeon to receive a Mythic+ update.

2. The Worldcore Raid

The Worldcore is the Season 3 raid, an eight-boss encounter set in patch 12.2 Eclipse. Players will pursue Xal'atath through the raid, fighting a combination of Titanic defenses designed to stop intruders and Xal'atath's lieutenants within the Devouring Host before the final confrontation.

Blizzard hinted to Wowhead that the Void energy used to open the Worldcore's door will be important, and asked players to "think about who's missing that we haven't seen lately." This suggests possible returning characters or cameo appearances tied to the raid's lore.

3. End-of-Season Title Changes

Season 3 introduces two significant changes to the title reward system, per Blizzard Watch:

Top 5% tier added. A new placement tier below 0.1% and 1% gives more players access to end-of-season titles. Based on prior seasons, this likely requires roughly 3,400 Mythic+ score minimum.
Spec-based achievements for 1% and 5%. The 1% and 5% titles (but not 0.1%) will be measured per specialization rather than across all players. A Frost Mage only needs to be in the top 1% or 5% of all Frost Mages, not the top 1% or 5% of all players.

This addresses a longstanding complaint: players on disfavored specs had to both push high scores and outperform the majority of the playerbase. Spec-based thresholds let off-meta players earn titles without competing against flavor-of-the-month specs.

4. Prey, Delves, and Astalor

Prey, the seasonal solo content system, picks up a new difficulty mode called Agony in Season 3. The Nemesis for the season is Astalor Bloodsworn, whose "relentless pursuit of anguish as an energy form to defend Azeroth has evidently warped his mind." Blizzard notes it is not a simple "he's corrupted" story arc.

Valeera will be the Delve buddy for Season 3, with her Curios and Delve challenges flavored by Astalor's ongoing presence.
