Patch 2.1.2 (Undocumented Changes)

From WoWWiki

See also: Patch 2.1.2 (Release Notes) for the "documented" changes

General

• Stackable items from mail now automatically stack if sum of stack sizes is not above stack limit. If you pull out of mailbox two stacks of cloth with 11 and 10 items in them, they'll still appear in inventory as 10 and 11, not as 20 and 1. 10 and 10 would stack automatically fine.

Priest

• The icon for Power Word: Shield now dims and lights correctly when the Priest has buffs set to self cast when they lack a friendly target.

Warlock

• Warlock pets will no longer regain all of its mana after dismounting.
• Banish can no longer be broken by casting it a second time.
• Soulwell will no longer play a sound when right-clicked.

Items

• Aquadynamic Fish Attractor now has a ten minute duration, although the tooltip still says five.

• Singed Pages from Karazhan books can now be sold to vendors for 15s.

Quests

• Quest Reward from Escape from Skettis changed to Volatile Healing Potion and Unstable Mana Potion
• The Skyguard Prisoner for the quest Escape from Skettis starts running after you kill the spawned encounter.
• The Netherwing quest Zuluhed the Whacked now requires you to kill Zuluhed and rescue Karynaku, preventing you from completing it with somebody else's key

Karazhan

• Moroes' gouge is now a stun effect, not an incapacitate effect.
