WOW Power Leveling: Only one of the three gathering quests may be completed each day
The quests you receive WOW Power Leveling from the Taskmaster vary by your professions. Herbalists will be required to collect 40 nether-dust pollens from the nether-dust bushes found around the area while miners are required to mine 40 nether-cite ore in the deposits found in the area.
Skinners will be asked for 40 Nether-mine Flayer Hides. Only one of the three gathering quests may be completed each day. Players without a gathering profession will receive a quest to gather crystals from the bodies of mobs they have killed.
Standing near the Taskmaster you will see the goblin Yarzill the Merc. He is your guy on the inside. He gives you more daily quests to help increase your reputation. His quests include poisoning the peon camps, collecting Nether-wing relics, and finding Nether-wing Eggs (these can drop from any creature or item node on the ledge).
When you get your reputation with Nether-wing to friendly, you will have more quests available. The majority of these will be daily also. You can also continue the earlier repeatable quests.
Do these new quests until you reach honored reputation? Now you will have more quests available to you (starting to see a pattern yet?). Your combat pet will be upgraded so that you can summon a combat pet in all zones.
