This quest gives 3 great wands for its level, and they will serve you well for quite a few levels. They either boost your +fire, +frost or +arcane damage.

The quest is not hard to do, but finding the quest giver can be quite difficult, who is located in the middle of Dustwallow Marsh, a level 45 zone. If you keep frostnovaing, popping up mana shield, blinking etc, however, you should be fine.

The quest series start at your mage trainer at level 30, so go speak to him/her. Don't miss this quest, I see lots of mages at level 40 who use worse wands because of this.

I did these quests with help from a 70 friend, achieving the wand at lvl 30. I was also able to make it fairly easy to Tabetha's location both times.

Like Calminaion said, just need to follow these quests:

https://vanillawowdb.com/?quest=1947 https://vanillawowdb.com/?quest=1947 (Obtained at your Trainer at level 30)
https://vanillawowdb.com/?quest=1948 https://vanillawowdb.com/?quest=1948
https://vanillawowdb.com/?quest=1949 https://vanillawowdb.com/?quest=1949 (3-Quest Chain)

Brought the quest's back completed, she said some stuff then bam I got the wand quest. She did some more stuff then I turned in the quest for a badass wand at level 30.

The moral of this story is, YOU CAN GET THIS WAND AT LEVEL 30.

The first time you run down here, be sure and go to Mudsprocket for the flight point. It'll save you several long runs in the future.

As of patch 3.0, these now all have the same stats (3 int, 7 spellpower). I would advise taking a wand that is NOT the same as your main spec, so that you can use it against mobs that resist your main school to supplement your off-spec spells.
