This is still the first version which may contain some errors or inconsistancies. Please report them in the comments so I will be able to fix it. Also suggestions to add quests I may have missed are welcome.
To begin, it is expected that you have done the Deadmines and are in possession of the Unsent Letter which VanCleef drops, or have one of the follow up quests in your log. If you don't have it, you're going to miss a lot of xp and one of the best rings you can get at low level, so do the Deadmines first if you don't have it. Also, if you have quested in Darkshore, it is expected that you have the quest “The tower of Althalaxx” where you are required to deliver a letter to Delgren. If you don't have this quest, don't worry too much about it, it's completely optional.
Items needed:
1 Bronze Tube
4 Minor Mana Potions
2 Elixirs of Minor Fortitude
Buy these from the AH or make them as soon as possible.
This guide starts in Auberdine, if you're there already make it your home. If you're on the eastern continent, this means you have to travel through the Wetlands and take the boat there. Feel free to take the quest “The Algaz Gauntlet” in north Loch Modan and the quest “Daily Delivery” while going there, but we'll deal with those later. Also, if you're on the eastern continent, make Menethil harbour your home instead of Auberdine.
Darkshore
Optional: In Auberdine get the quest “Trek to Ashenvale” from Sentinel Selarin. She's only around when someone completes "A Lost Master", so just skip it if you can't find her. It's just a nice bonus when you're traveling to Ashenvale, but it is not required.
Travel south the grove of the ancients and get the quest “The Sleeper Has Awakened” from Kerlonian Evershade at 44,76. If he's not there it probably means someone else is doing this quest, you can either skip it or wait for hin to respawn. Get the horn from the chest and get back to the road and continue south. Whenever Kerlonian falls asleep, use the horn to wake him. As soon as he says anything else besides that's he's sleepy, it means some enemies are coming. If you run north immediately, you can avoid fighting them all at once, but if you can't avoid the fight be sure you both survive. If you fail this quest it's probably going to take longer for him to respawn than it's worth, so just abandon it and move on.
