As a part of the transition from Mists of Pandaria to Warlords of Draenor, we'll be making some changes to the Legendary Cloak quest line.
no
you have to go to a website and download quest helper. i recommend you google "WoW quest helper download"
You must go back to the quest giver and accept the quest again. Or if possible, have a friend in your group share the quest with you.
Quest and do your lvl instances
WoW, Ragnarok Online, etc.
A lot like Runescape WOW and a lot more!
You cant play as a Naga in WoW, but there is a quest in Desolace that lets you have a Naga disguise. This also gives you the ability to breathe underwater, throw harpoons and nets and makes you friendly with the Naga, however, the disguise is only available while the quest is active.
Any of Stormwind's guards are capable of completing the quest, however, this is a seasonal quest and not available when the holiday is over.
If you mean that you have destroyed the cask but kept the quest, the only way to get it back is to return to the questgiver in Westfall, abandon the quest and retake it from the Dwarf. I do not think the quest itself is repeatable, so if the quest is completed, you cannot do it again.
A PVP quest is treated just like any other quest you'd pick up, except the usually obvious objectives relating to pvp; "Capture a tower in warsong gulch" For example
The Quest Helper mod for World of Warcraft can be downloaded from the Curse website listed below. You do not need the curse client to install it to your game, although it makes it easier. Just install it like any other addon, to your addons directory of your WoW interface folder.
You will get the quest once you have done all of the quest line in Dragons Blight. At the end of the cut scene the dragon queen will send you back to Borean Tundra which will then send you to Thrall in Org to pick up the quest Battle for under city.
