This guide starts at level 30. It is your task to reach that level on your own and it shouldn't be a problem, you can check the other leveling guides in our leveling guide forum for the earlier levels. The main reason why I don't want to start a guide at level 1 is because:
This guide is optimized for FAST leveling with a minimum of grinding sessions. Quests are important, they give rewards and faction and are less boring than pure grinding, BUT sometimes some quests are really a time waste and we will be skipping those and replacing them by good grinding spots when it is necessary. Some people say that Grinding is always faster than questing, this is true in theory when you don't know which quests to take and which to avoid, and what is the best order to do them. With this guide, questing will be very efficient and much better than pure grinding. Follow each instruction carefully and you will see for yourself. The quests choices and order to do them are optimal so that you run as few as possible while doing the most possible and then turning several quests at the same time. This guide will be very useful for both veteran and novice players, and this is why sometimes I describe things in two fashion "In short" (for the veterans) and "in details" (for the novices). That way the veteran players can skip those "in details" paragraph if the "in short" one was enough information for them. So even the guide itself is optimized for the minimum reading possible, to save time! Let's get started immediately then!
Everything described in this guide can be done solo (besides when I say otherwise). You can of course follow this guide while duoing, grouping, it's not a problem, it works too.
Here is a list of addons which I use. You will mainly need an addon to display coordinates because I use them to describe locations in my guide (x,y). The one I use is FuBarLocation, which requires you to install FuBar and Ace 2. Below I listed the files you must download and install, they can all be found on this page: http://files.wowace.com/
Side Note: In case you don't know how to install add-ons, make a folder called Interface in your World of Warcraft directory (if it doesn't exist already). Then you open it and create a folder called Addons inside the Interface folder (if it doesn't exist already). Now every Addon you want to install goes directly into the Addon folder. For example you download and unzip FuBar, you drag the folder called FuBar (not Interface or Addons) into the new Addon folder you created. You restart World of Warcraft completely and it should be working.
If it isn't you might need to log out to your login screen and click on "Addons" in the left lower corner. Tick the box that says "Load out of date Addons". Relaunch WoW.
Every time you pass by an auction house, try to buy the following items:
These might not always be up for sale, so start checking early.
Chapter 1 - [Level 30 - 41] Journey from Thousand Needles to Badlands
Go southeast along the mountain, keep going until you hit Roguefeather Den (27,51). It's grinding time! Don't worry, there will be a lot of questing after that, but you are gonna kill these harpies until those two goals are achieved:
The harpies are lvl 28-30, drop cash and silk cloth. There are a lot of them and they respawn fast. (Make sure to kill the harpies that are down on the ground and those that are in the cave up on the hill) With the 25 Vibrant Plumes you can get 60 Tickets at the Darkmoon Faire, you can then trade 50 Tickets for a 14 Slot Bag, which is a big plus at this level (unless you are a twink). Sadly the Darkmoon Faire is not always available, check this Darkmoon Faire Necklace Guide to know when the Darkmoon Faire will be available, and put your Vibrant Plumes in bank until then. If you don't want the bag, you can either auction those plumes (they sell nicely) or save them up for your future epic necklace.
Go east until you reach the Mirage Raceway in the Shimmering Flats(80,77). Get the following quests there:
You can find everything needed to complete those quests all around the raceway, do long circles all around it and kill everything on the way.
If you have troubles finding buzzards, there is a nice spot with 10 of them at (87,66).
Keep doing this until you complete all the quests, get 10 Turtle Meat and hit level 32. Grind on turtles in particular, they drop scales which sell nicely. Don't sell the Turtle Meat, put them in bank or somewhere in your inventory.
Turn in all the quests and get the follow up quests :
Before we leave, go south and zone into Tanaris. Go to Gadgetzan and talk to the Gryphon master on the other side of the town to get the new flight path. Hearthstone to Theramore, sell junk and repair.
Get out of Theramore and follow the road northwest and then south to the Barrens. In the Barrens go north then east to Ratchet. Talk to Gazlowe in Ratchet, get the follow up  Goblin Sponsorship. Also talk to Wharfmaster Dizzywig on the docks and get the follow up  Parts for Kravel
Take the boat to Booty Bay. In Booty Bay on the docks, talk to Wharfmaster Lozgil and get the follow up. Then go to the Inn in Booty Bay and make it your home location. Then go train new skills in Stormwind by gryphon ride (for rogues, there's a trainer on the 1st floor of booty bay inn). Visit the Auction house, repair, sell, buy 4 stacks of food/drink (of course don't buy drinks if you aren't a class with mana).
At level 32 the zone we will be aiming for is Stranglethorn Vale.
No need to take the Green Hills of Stranglethorn quests (the one with the chapters), it will just encumber your quest log for now. You will complete each chapter when you get the right pages. So while you hunt always look out for these:
Step 1: Kill River Crocolisks which can be found all along the river in northern Stranglethorn Vale until you find 2 Large Crocolisk Skins. While you search for crocs you can also kill Young Tigers close to the river for Tiger Mastery.
Step 2: Then kill 10 Young Tigers (or as much as you still got left)
Tigers can be found mostly south and around the Nesingwary camp.
Step 3: Kill Young Panthers, they are mostly found on the other side of the river to the east. (41,10).
Step 4: Go further northeast to the Kurzen Camp (44,11) and kill 15 Kurzen Jungle Fighters as well as Kurzen Medecine Men until you get 7 Jungle Remedies (might take a while). Also you'll need a Fern Extract from one of the piles of crates scattered around the Kurzen Compound.
Step 5: Once all 4 quests are done go turn them in (besides Supply and Demand, which you will turn in later) at the Rebel Camp where you get the follow up:
Step 6:And at the Nesingwary camp where you get the follow ups:
Step 8: Further southwest on the plateau you should find Stranglethorn Raptors, kill 10.
Step 9: Go south and down the plateau until you find the troll camp at Bal'lal Ruins (29,20)
It should take a while to get 15 bloodscalp ears but it is a nice grinding spot anyway. So grind at this spot until you hit level 33. If you don't have enough trolls there is another camp northeast at the Tkashi Ruins (33,15).
Step 10: From the troll camps, go west until you hit the shore, and move along the shore towards the north until you find Crystal Spine Basilisks. If you run short on Basilisks, there is more on the lower plateau to the east along the shore. If there aren't any basilisks just go kill some trolls until they respawn. Kill basilisks until you get 10 Singing Crystal Shards.
Step 11: After that, take a swim westwards until you hit the island at loc (21,22), you will have to go towards the middle of the island so the quest  The Stone of the Tides is completed, but be careful with the lvl 37ish elementals on the isle.
Step 12: When you completed all 6 quests, go turn in the 3 mastery quests at camp nesingwary and get the follow ups:
Check if you completed any of the chapters of the Stranglethorn pages quests as well and turn them in if you did.
Make sure you repair and sell junk at the vendor before you go again. You will probably need a lot of space in your bags with the extra pages you will find.
Step 13: Now you probably must be about halfway to level 34. It's time to go grind at Kurzen camp or on the Trolls, up to you. When you are 1 bubble away from lvl 34, warp to Booty Bay.
When in Booty Bay. Turn in the following quests:
Step 5: Get follow up quests:
Since you are lvl 34 now, go train if you wish to do so. Closest place to train is Stormwind by gryffon. (Unless you are a rogue, there's a rogue trainer on the 1st floor of Booty Bay inn).
While you are on gryffon (or in Booty Bay), ask in general channel if anyone has any page you need, and trade your spare pages in exchange or just buy them, they go for 10-15 silver on average. You can also check the Booty Bay auction house for missing pages. I suggest you even buy them overpriced (Offer 20-30 Silver for a page and you should get it quickly). The sooner you complete the page collection, the better for your bag space . Anyway, time to hunt again!
Step 1: When you are done, go back to the jungle, follow the road north until you hit loc (39,22). And go westwards (towards the area north of Grom'Gol Camp). You should find plenty of Lashtail Raptors there. Kill them as much as needed for the quests.
Step 2 & 3: When done with raptors, you should hit the river to the east and search along the banks for Snapjaw Crocolisks. At the same time you can start heading to the Venture co. Camp next to Lake Nazferiti and kill Geologists there (44,20), they drop the "tumbled crystals" you need for  Hostile Takeover. You can find crocolisks on both sides of the river, all around Lake Nazferiti and all the way down to Mizjal Ruins. Keep killing Goblins and Crocolisks until you get both quests complete.
Step 4: When done with that, head northwest until you hit the area in between Bal'al Ruins and Tkashi Ruins (33,15). There you wil find Elder Stranglethorn Tigers and kill 10 of them.
Step 5: Once done, go to Nesingwary Camp and turn in
Step 6: Go northeast until you hit the Kurzen Camp, this time go straight for the cave there and kill Commandos and Headshrinkers. Careful the Commandos are stealthers.
Step 7: When done with that go southwest to find Sin'dall. Sin'dall is on top of a hill at (31,17) right in the middle of Bal'al and Tkashi ruins. It is definitely soloable at lvl 34, just make sure all your long cooldown abilities are up.
Step 8: Once Sin'dall is dead, head west until you hit the island you discovered before (21,22), and kill Water Elementals there until you get 6 Water Elemental Bracers.
Step 9: At this point you should be getting close to level 35. If you are not, grind on trolls until you are about 3 bubbles of XP away from it.
Step 10: When that is done, go turn in your quests at the Nesingwary and Rebel camps, at the Rebel Camp get the folllow up  Kurzen's Mystery. By now you should have completed your page collections or be close, if you aren't it's ok, we will be back in Stranglethorn Vale in about 3 levels and then you ll for sure complete it.
Step 11: Warp to Booty Bay, turn in the quests
Time to travel!
If you already know how to get there, go to Southshore in Hillsbrad Foothills (or take a Gryffon Ride)
If you don't know how to get there:
Take a gryffon ride to Stormwind, then use the tram or gryffon to Ironforge, then gryffon ride to Southshore or Arathi. If you don't have those flight paths, fly to Wetlands. From Menethil in Wetlands follow the road east and then north until you zone into Arathi Highlands; keep going north until you reach Refuge Pointe (46,46). Get the flight path there. From Refuge Pointe take the road west until you reach Hillsbrad Foothills. In Hillsbrad Foothils follow the road west and then south at the 3rd fork. Southshore is at loc (50,55). Talk to the Gryphon Master in Southshore. and bind at the Inn. You should be level 35 or close by now.
Gather all the quests in Southshore, you should have:
Don't bother with  Bartolo's Yeti Fur Cloak unless you are a Leatherworker or got a Leatherworker friend who can make a Hillman's cloak. You can buy a Bolt of Woolen Cloth at the auction house or ask a tailor.
Let's start with some Murloc slaughtering!
Step 1: The murlocs are right next to the town on the western shore. Kill 10 Tidehunters and 10 Oracles.
Step 2: Go turn it in and get the follow up. Go back and kill more murlocs until you get 10 Murloc Heads.
Step 3: Go turn in the quest, get the follow up. Speak with Marshal Redpath in Southshore, get follow up and talk to Lieutenant Fahren again. Get the follow up  Stormwind Ho!
Sell and repair (there's an armorsmith behind a small house next to the inn)
Step 4: Time to hunt Nagas now. The ones you need are on the eastern shore, right next to the town. Kill 10 Daggerspine Shorehunters and 10 Daggerspine Sirens, go back to Southshore and talk to Lieutenant Farren again and get the follow up  Reassignment.
Step 5: Now take a flight path to Refuge Pointe (Arathi Highlands). In Refuge Pointe get the quest  Worth its Weigh in Gold from Apprentice Kryten.
Step 6: Go southeast until you reach the Go'Shek Farm (60,53) and find the NPC named Quae, she is looking over the Go'Shek Farm from the northwest edge. Talk to her and take the follow up quest  Hints of a new Plague?. You need to find and kill a Forsaken Courier and loot a Sealed Folder from him.
In Short: The Forsaken Courier roams from the Go'Shek Farm all along the road up until the wall to Hillsbrad Foothils. He is lvl 35 and doesn't have that much hit points, but he has 4 level 35 bodyguards. Find a way to kill and loot the Courrier. You can do it solo at level 35, I've done it with 5 different classes and I've heard about other players doing the same. For instructions on how to kill the courier with a certain class, see below.
In Details Now you need to find and kill the Forsaken Courier, he roams from the Go'Shek Farm all along the road up until the wall to Hillsbrad Foothils. He has 4 bodyguards, all level 35.
There are many ways to kill it though, even solo at level 35.
Step 7: Once you got the Sealed Folder from the Forsaken Courier, go back to Quae (60,53). Turn in and get the follow up  Hints of a new Plague?, where you have to escort Kinelory.
For the escort, one word of advice: Let Kinelory be in the front, always walk behind her, when mobs aggro her, help her take them out one by one. And make sure they don't run far. Kinelory is quite a tank and can also heal a bit. If you let her be in front and don't let runners create trains, you will complete the quest easily.
Step 8: When completed, talk to Quae and get the follow up. Then go southeast of Go'Shek Farm to the troll village (63,65).
Kill trolls until you get 10 Tusks. Kill Witch Doctors until you get 4 Medicine Pouches. Further inside the village and to the south (68,75) you will find a cave. Inside the cave you will find Witherbark Shadow Hunters and get the Hunter Knife you miss to complete the quest.
Step 9: Once completed, run back to Refuge Pointe in Arathi and turn in the troll quest.
Hearthstone to Southshore, and talk to Phin Odelic and complete the quest "Hints of a New plague".
Sell and repair.
Step 10: Go north and follow the road north until you zone to Alterac Mountain (96,47). A bit further up and to the right you will find Soferan's Naze (58,67). Clear the Syndicate camp there, and in the middle of the camp on a table you should find parchments named "Syndicate Documents". Right click one of them and get the two quests  Encrypted Letter and  Foreboding Plans.
Then go northwest towards the snowy mountains where you will find Crushridge Ogres, they drop the Dirty Knucklebones you need.
When you run short on ogres, you can go to the southwest where you will find the area called "Corrahn's Dagger" (47,76). There you can kill Syndicate Footpads and Syndicate Thieves as well as Mountain Lions and Hulking Mountain Lions. I suggest you go back and forth from this spot to the ogres whenever you run short on mobs. Do this until the Ogre and Syndicate quests are completed. Then there's more Lions further to the west at "The Headland" (38,55).
You should keep going westwards while killing lions until you complete your quest. At this point you should be close to level 36, if not, grind on ogres / syndicates until you are about 2 bubbles away from level up.
Step 11: Go northwest towards Dalaran until you reach Archmage Ansirem (18,78). Turn in the quest  Magical Analysis and get the follow up  Ansirem's Key. Then warp to Southshore or run there if Hearthstone isn't ready.
Turn in the 5 quests in Southshore. Get the follow up  Letter to Stormpike from Loremaster Dibbs. Don't get the other follow ups.
Congratulations on level 36.
Step 1: Take a gryphon ride to Ironforge, go to the hall of explorers northeast of the Gryphon master and get the quest from Roetten Stonehammer  Reclaimers' Business in Desolace. Also turn in the quest  Letter to Stormpike at Prospector Stormpike in the Hall of Explorers, don't get the follow up. Then go to the inn of Ironforge and bind yourself there.
Step 2: Fly to Stormwind. Repair, sell stuff and train new skills. Also, go turn in  Reassignment, at Major Samuelson in Stormwind Keep. (72,16)
Step 3: Fly to Booty Bay. In Booty Bay, turn in the quest  Ansirem's Key at Catelyn, she is on the 1st floor inside the Booty Bay in. Get the follow up  "Pretty Boy" Duncan.
Step 4: Take the boat to Ratchet. And then:
Talk to the Hyppogryph master.
Then get quests:
Then go in the big building and talk to Dalinda, get the follow up quest  Search for Tyranis. Tyranis is in the other building (the smaller of the two), southwest of the main one. Kill Tyranis and loot the pendant.
Go back to Dalinda. Before you talk to her, clear the whole building. After you talk to her she will start to walk out of the fortress, escort her and make sure she doesn't die.
Warning: Dalinda is one of those stupid escort NPCs who don't stop when YOU are attacked. So let her in the front and make sure she gets hits first. Once out of the fortress she will run away and you will get a "Quest Complete" message.
At this point you should be level 37 already. If not, you should keep on grinding on Centaurs until you hit level 37.
This session started with the Satyr quest and finished right now after turning in all the quests in Nijel's Point. That was done with a level 36 character with average gear, solo, on a new server (no twink). I've tried it with 3 different classes and it works just as well. And there is still two quests to turn in, that's just to show how efficient the quest path of desolace can be when done the right way.
Warp to Ironforge, go to the Hall of Explorers and turn in the quest  The Karnitol Shipwreck.
At this point, you got 2 options:
In Badlands kill any Buzzard or Coyote you find on your way.
 A Dwarf and His Tools
also get quest  Barbecued Buzzard Wings from Rigglefuzz.
Note: Whenever you need to sell or repair, go to this spot. There is a goblin smithing supplier and it's the only vendor and repairer in Badlands.
Get  Coolant Heads Prevail, turn it in, get the Follow up Gyro...What? and turn in.
At (53,34) under a tent next to a big keg you will find a Crumpled Map on the floor. Click it and get the quest  A Sign of Hope. Then keep on killing Dark Dwarves until you get Ryedol's Lucky Pick.
When you got the crate, go back to Prospector Ryedol south of Hammertoe's Digsite and turn in the quests.
Get the follow up  Scrounging from Sigrun Ironhew.
When that is done, go east to Martek the Exiled (42,52) and turn in the quests  Indurium and get the follow up  News for Fizzle. Turn in  Barbecued Buzzard Wings to Rigglefuzz as well. Repair and sell while you are here.
Then go northeast and turn in  Scrounging at Sirun Ironhew.
After that go west to Lotwil Veriatus and turn in the quest, get the follow up  Study of the Elements: Rock.
You should be getting close to level 40 at this point, about 35000 xp to go normally, if you still follow the "kill everything on your way" rule. Go grind on Rock Elementals or Lesser Rock Elementals, Dark Dwarves or Troggs. There are a lot of Dwarves at the Angor Fortress. It's up to you. Should take about 1h30 of grinding.
It went quite well for me, I was doing 41000 XP/Hour before I got to the grinding part. This is my XP rate starting from the moment I talked to Propector Ryedoll until level 40.
So that's approximately 1 level and a half in 4 Hours. If you can do better, I would love to know!
Complete  This is going to be hard and get the follow up. Talk to Lotwil and complete the quest but BEFORE you accept the next step from Lotwil, be warned: A level 45 Elemental will spawn and you will have to defeat it. At level 41 this is hard but possible for every class. Just use every long cooldown ability you have as well as potions. Loot "Lotwil's Shackles of Elemental Binding" from the Fam'retor Elemental and go turn in the quest to Lotwil. Congratulations, you are done with Badlands and with the first Chapter of this leveling guide! Warp to Ironforge and sell / repair / auction etc.
