WoW Patch 12.1.5 Notes: Kith'ix Raid, Labyrinth of Kindo'jan and Venomstone Upgrades
Midnight's 12.1.5 update lands October 13 with a one-boss raid, a nine-chamber mega-delve, Aqir Invasions, Venomstone gear upgrades and class tuning. Here's what matters.
Blizzard has published the full notes for World of Warcraft: Midnight's 12.1.5 content update, and it's a bigger mid-season patch than the version number suggests. The update goes live with weekly maintenance on October 13, 2026, and brings a new single-boss raid, a Delve-style mega-dungeon, zone-wide Aqir Invasions, a way to push Season 2 gear past its current ceiling and a round of class changes. The notes went up on October 1; below is everything worth knowing before the servers come back up.
TL;DR
- The Unbinding of Kith'ix – a one-boss raid beneath the Venomous Abyss, with Lady Liadrin fighting at your side. Story Mode, Raid Finder, Normal, Heroic and flexible 15–25 player Mythic.
- Labyrinth of Kindo'jan – a nine-chamber, Delve-like mega-dungeon with Valeera Sanguinar as your companion and Mythic-level gear rewards.
- Aqir Invasions – hourly ten-minute public events in Eversong or Zul'Aman that end in a boss fight.
- Ascendant Venomstones – collect ten to raise the item level of a fully upgraded Season 2 Hero or Myth piece.
- Keystone Myth returns – reach 3600 Mythic+ rating for a title and a mount.
- Notable tuning for Devourer and Void-Scarred Demon Hunters, Marksmanship Hunters, Protection Warriors and Restoration Druids.
The biggest changes
A new story chapter and a one-boss raid
The new campaign chapter, "The Promise of Tomorrow," picks up after Ula'tek's defeat, which has left the restraints on Kith'ix, a C'Thraxxi general bound beneath the Venomous Abyss, failing. You'll have to keep the fragile peace between Quel'Thalas and Zul'Aman before heading down into the Coiled Isle to face him.
That fight is The Unbinding of Kith'ix, a single-boss raid with Lady Liadrin as a companion. It covers every difficulty from Story Mode to Mythic, and Mythic uses flexible sizing for 15 to 25 players. That makes it a lot easier for smaller Mythic guilds to field a roster.
Labyrinth of Kindo'jan
The other headline addition is the Labyrinth of Kindo'jan, set in an Amani funeral complex. Think of it as a mega-Delve: nine chambers, Valeera Sanguinar as your companion, and rewards that go beyond normal Delves, including Mythic gear, cosmetics and titles. You can clear it in one sitting or tackle it one wing at a time, and every extra room you push through adds both treasure and risk. Blizzard also lists a Tier 11 solo challenge for players who want to test themselves.
Aqir Invasions
Aqir Invasions are new public events in either Eversong or Zul'Aman. For ten minutes each hour, players across the zone complete scenarios and then team up against a boss. There are six scenario types (three combat, three non-combat), and combat scenarios roll one of eight affixes, from Void Sphere and Aqir Elites to Swarms! and Web Weavers.
Season 2 mid-season refresh
This is the part most max-level players will feel first.
| Feature | What it does |
|---|---|
| Extra bonus roll | Orin Straylight in Silvermoon City offers one additional Nebulous Voidcore per week through a quest chain, paid for with gold, Voidlight Marl or Veteran Mistcrests |
| Ascendant Venomstones | Drop from Heroic and Mythic raid bosses, Mythic+ keys at +10 and above, Tier 11 Bountiful Delves and Nightmare Prey Hunt chests |
| Venomstone upgrade | Ten stones raise the item level of a fully upgraded Season 2 Hero or Myth item, or a max-quality Tidal Crafted weapon, trinket or necklace |
| Crest cap | Lifted the week of October 20 |
The rollout is staggered. The Orin Straylight questline started with the week of October 6, the next step ("Ancient Depths, Ancient Venom") arrives the week of October 13, and the research finishes the week of October 20 with "Ascending with Venomstones." If you haven't picked up the pre-patch quests yet, start with "In the Catalyst's Shadow" from Decimus in Voidstorm and "Prismatic Potential" from Orin.
Mythic+ players also get Keystone Myth back. The new achievement, Midnight Keystone Myth: Season 2, requires a rating of at least 3600 and awards the title "the Venomous Contender" plus the Timelost Saddle. Three achievements (Snake Eyes, Snake Eater and Good Night, Sweet Prince) are no longer needed for Glory of the Wartorn Hero.
Class changes worth knowing
- Demon Hunter (Devourer): Collapsing Star no longer goes on a 5-second cooldown when you cancel it, gains extra range once the cast begins, and its Fury-drain slowdown is now limited. Soulforged Blades' crit bonus rises from 15% to 18%, and several talents (including The Hunt and Eradicate) have moved in the tree.
- Demon Hunter (Void-Scarred): Monster Rising's Intellect bonus outside demon form drops from 15% to 10%, but its Collapsing Star damage bonus rises from 15% to 20%. Demonic Intensity now lets Collapsing Star reset The Hunt and boosts its empowered damage by 30%.
- Hunter (Marksmanship): Unload is gone. The new talent Blood Fletching makes Aimed Shot crits apply a bleed. Explosive Shot also stops auto-targeting when you press it without a target.
- Warrior: Protection's Execute deals 30% more damage, and Colossus' Practiced Strikes now also cuts the Rage cost of Execute and Revenge by 10.
- Druid (Restoration): Nature's Bounty is redesigned so Regrowth splashes 15% of its healing onto up to three allies with Rejuvenation, prioritizing the most injured.
- Evoker: Scalecommander's Melt Armor damage doubles for Augmentation, while Preservation's Merithra's Blessing drops from one minute to 30 seconds.
- Priest (Discipline): Master the Darkness is cut from one minute to 30 seconds.
- Rogue (Outlaw): Deft Maneuvers' Blade Flurry bonus now scales at 5 Energy per target hit, up to 30, instead of a flat 30.
Quality-of-life and other changes
- Player coordinates now appear under the minimap, with options to hide them or switch between whole numbers and decimals.
- Raid frames can show an animated border and a pulsing overlay on anyone you can dispel.
- A new "Pulse Your Health" audio alert plays a looping sound under a health threshold you choose, getting more urgent as you drop.
- Legion and Battle for Azeroth reputations are now shared across your Warband.
- Prey catch-up: players below rank 4 earn a full rank of Journey progress per hunt.
- Housing gets floor up/down keybinds in floorplan edit mode and cleaner blueprint dye lists.
Bug fixes and recent hotfixes
The 12.1.5 notes fix a Murder Row issue where Zaen Bladesorrow's Murder in a Row could mark a safe spot you weren't hiding behind, plus a long list of Frost Mage and Survival Hunter interactions.
Ahead of the patch, Blizzard's October 6 hotfixes also adjusted the current raid's Ula'tek encounter (lower damage and add health in several places, and Caustic Waves on Mythic now emits three waves instead of seven). The same round buffed Devourer Demon Hunters, Brewmaster and Mistweaver Monks, Subtlety Rogues and Enhancement Shamans, and halved Unholy Death Knight's Blightfall payout from 200% to 100% of remaining plague damage.
What it means for players
12.1.5 is a classic mid-season catch-up patch with real new content attached. Raiders get a fresh boss and a flexible Mythic format, solo players get the Labyrinth as a serious gearing route, and everyone at max level gets a weekly reason to log in thanks to the extra Voidcore and Venomstone upgrades. Just remember the staggered timing: the gear ceiling only really moves once Orin's research wraps up in the week of October 20.
