Hotfixes/2009 Archive - WoWWiki - Your guide to the World of Warcraft

entre las cosas q encontre estan:

The Black Knight will now drop a Frozen Orb in heroic difficulty.

When immune to the stun of following abilities, Maim, Bash, and Hammer of Justice will no longer cause player spells to be interrupted but they will still interrupt NPCs. Also, when these abilities do stun a player target, they will not perform an interrupt effect and lock out the affected magic school.

The duration of Kologarn's Crunch Armor effect has been greatly reduced in normal difficulty. This change negates the explicit need to tank swap Kologarn

The paladin ability Vengeance can no longer be spellstolen

Demonic Circle will no longer allow you to teleport to a location within the sewer pipe in the Dalaran Arena and result in an error message instead.

Raise Dead now properly detects the presence of Corpse Dust in your inventory.

Tremor Totem now properly pulses every 3 sec (fijense pero creo q proccea cada 4)
