If the primary attack of Hammer of the Righteous fails to hit the target due to miss/dodge/parry/block, no enemies will be affected by the area-of-effect attack. Rogues who are under Cloak of Shadows, however, are able to resist this damage.
 * The Warp Stalker ability Time Warp (pet) can no longer be used on paladins with the Divine Shield buff active.

This issue has been fixed so that players cannot queue for both Battlegrounds and via the Dungeon Finder under these select circumstances.
 * Battle for Gilneas
 * The banners at each capture point now take 8 seconds to capture, up from 5.

 * The guild achievement Lower Blackrock Spire Guild Run can now only be earned in a group of at least 4 players from the same guild in a 5-player party.

 * Classes
 * Death Knights
 * Necrotic Strike is now affected by resilience.
 * Druids
 * Druids previously unable to learn Nature's Grasp will be able to learn that spell now.
 * Rejuvenation now consumes 16% of base mana, down from 26%, but still requires 26% of base mana in order to be cast.
 * Mages
 * Rank 1 of Pyromaniac no longer improperly gives 5% passive haste.
 * The mana costs of the following mage spells have been reduced, but they still require the previous percentage of base mana in order to be cast: Arcane Barrage (11% of base mana), Arcane Blast (7% of base mana), and Fireball (12% of base mana). As an example, Fireball requires 16% base mana to cast, but only consumes 12% of base mana.
 * Priests
 * Sin and Punishment is now properly causing its terror affect when dispelled. In addition, it no longer shares diminishing returns with fear effects. It now shares diminishing returns with horrify effects.
 * Priests who were unable to learn Holy Nova will now be able to train the spell.

 * The battle resurrection counter will now correctly reset if players are not inside the dungeon when an encounter resets.
 * The Bastion of Twilight
 * The hotfix on January 5 to increase the damage of Liquid Ice during phase 3 of the Ascendant Council fight has been reverted. Due to a separate bug with the size of the Elementium Monstrosity's hitbox, it is often impossible for melee classes to avoid damage from this ability. This issue is slated to be addressed in patch 4.0.6 so that Liquid Ice damage can again be increased.
 * Many adjustments to the behavior of various mechanics in the Sinesetra encounter have been made.
 * Fester Blood now hits everyone in the room instead of having a 20-yard radius on Heroic difficulty during the Cho'gall encounter. No more kiting he who has too many eyeballs.

 * Blackwing Descent
 * Atramedes will now reset if the players targeted by Sonic Breath or Obnoxious Fiends attempt to leave the room.

Entering combat with Atramedes forces the gongs to become usable and the fight will function normally from this point.
 * Atramedes will no longer despawn when his tail passes through the area trigger in the entrance to his room. He will no longer despawn randomly during the fight. Pulling him out of his room will now cause him to reset.
 * The damage of Chimaeron's Caustic Slime has been reduced for both raid sizes and dungeon difficulties.

 * Free Action Potions now cannot be used above level 80.
 * Professions
 * Archaeology keystone fragments can no longer be prospected.
 * Lifebound Alchemist Stones can no longer be disenchanted.

January 6

 * Classes
 * Death Knights

 * Shapeshifted characters should no longer be unable to jump on the rope during the Vanessa VanCleef encounter. They will now be pulled out of a shapeshift form automatically. In addition, players should no longer lose pets when jumping on the rope (they will respawn when the player lands after swinging). Please note that until a client-side patch can be applied, an inappropriate aura will be displayed when pet classes or shapeshifted characters use the rope. The tooltip of this aura will read "Delicious Aura (UNUSED REUSE) / Instant / Delicious food increases haste by 10%" and can be disregarded, as it does not provide a haste buff. It's an aura of free word association... Enjoy!
 * Lost City of the Tol'vir
 * Tamed Tol'vir Prowlers now have regular loot and Skinning tables, instead of epic-quality loot.
 * Throne of the Four Winds
 * Al'akir's Static Shock now does 5,000 damage and only interrupts the spell the player is casting at that moment. It doesn't lock out the caster and only casts every 5 seconds or so.

 * Quests & Creatures

 * General
 * Mix Master (guild achievement) is now awarded at 1,000 flasks, down from 10,000, and Better Leveling Through Chemistry (guild achievement) is awarded at 3,000 flasks, down from 25,000. It turns out we overestimated these numbers just a smidgen. More information can be found here.
