In the latest round of hotfixes, Blizzard re-enabled the ability to skip some Profession tutorial quests, and Wrath Classic also received some fixes with Phase 2 now live.

Classes

Warlock

Fixed an issue where Grimoire of Synergy would not function while Grimoire of Sacrifice was active.

Dungeons and Raids

The Nokhud Offensive

The Raging Tempest

Surge of Power can no longer be removed with player immunities.

Mythic+

Azure Vault

Leymor

Explosive Affix – Volatile Saplings no longer spawn Explosive Orbs.

Professions

We have re-enabled the ability to skip some profession tutorial quests.

Wrath of the Lich King Classic

Auction House

Added options to sort by Buyout Price and by Unit Price. These can be selected via a gear icon button to the right of the search sorting headers.

Now, when you select an item to purchase, the total buyout price is displayed next to the Buyout button.

Searching an item name in quotes will now perform an exact match search for that item name.

Shift-clicking an item with the Auction House open will now paste the name of that item in quotes to the Auction House.

Creatures and NPCs

Class trainers were inadvertently forgetting to charge money for the dual talent specialization, profession respecialization, and other paid options. While we investigate the cause of their inadequate accounting practices, we’ve asked them to stop selling the dual talent specialization ability. Anyone who has already purchased dual talent specialization will be allowed to keep it, and we’ll re-enable it once we’ve fixed the issue. The profession specialization services will continue to be offered, but may spontaneously start charging their intended fee.

Dungeons and Raids

Defense Protocol Alpha

Bounty Satchels from Heroic Daily Dungeons, with Defense Protocol Alpha active, are no longer tradeable to party members.

The Frostbite effect from Heroic Utgarde Keep and Heroic Utgarde Pinnacle, while Defense Protocol Alpha is active, now appears as a debuff and cannot be cancelled via the UI.

The Bounty Satchel from the Heroic Daily Dungeon, when Defense Protocol Alpha is active, is now multidrop. This was an accidental oversight and was always intended to be multidrop. This means all members of the party can loot the item and receive 3 bonus Emblems of Conquest.

Obsidian Sanctum

Sartharion

Now drops an additional item when 2 or 3 drakes are alive, similar to 3.4.0.

10-Player now drops Reins of the Black Drake (instead of Reins of the Twilight Drake) when 3 drakes are alive.
