Julia, The Pet Tamer

Here is my Quicklist Guide to the Alliance Side of the Pet Trainer Intro Quests. This is a quick reference to see what type of pets you will need to defeat the trainers easily. On Trainers who have the same type of pet for all 3 pets in their party, I would recommend you bring at least two pets that are the opposite type (i.e. bring three appropriate leveled Mechanical types to fight three trainer Beasts). Don't rely on fighting all three of their pets with just one of yours, despite the fact that they will have stronger attacks and defeat them quicker.

*Author's Note: In writing this guide, I used various references from wowhead and warcraftpets.com. I did not write this guide as I was doing each trainer. Some information might be wrong. Please feel free to comment and I will change it as needed.

Although you can complete this quest on a horde character, if an alliance character on your account picks it up, you will be unable to accept the next quest in the chain from the NPC that you just defeated and your alliance character will have to run to the master to accept it for you.

I completed this whole chain by running a Level 23 Alliance character to each of the trainers to accept quests. As I didn't have a high level Alliance character to escort, I simply followed on my Horde druid killing any mobs nearby. The highest level are the chain takes you to is Southern STV and if you follow the road there are only a few places that you will definitely pull aggro and have to corpse run. Even so, I suggest you do it on a NElf for Wisp.

She is found in Elwynn forest, not in Stormwind City. I made this mistake and was flying all over Stormwind looking for the Stormwind Vineyard that was never there. Hopefully this will help others not make the same mistake.
