Supplies are on the way, she says, but she doesn't want to waste time while she waits. She sends you to retrieve three pieces of Darkspine Iron Ore. You won't be mining for this ore, nothing as simple as that. You need to kill Darkspine Myrmidons along the eastern coast of Quel'Danas. They drop Darkspine Chest Keys which are then used to open chests along the naga encampments. The Myrmidons fight like really boring Warriors, using Sunder Armor and Demoralizing Shout. The area is also lousy with Darkspine Sirens, which fight like Frost Mages. Ice Armor, Frostbolt, Frost Nova, that sort of thing.
You'll likely need to do quite a bit of fighting to get your three pieces of ore, simply because there are so many mobs in the area. Once you work into a rhythm, it should only take as long as 'Arm the Wards!' does each day. While this quest may seem like one of the more time consuming Quel'Danas dailies, it is certainly worth the effort. Why? Because when this quest is completed a certain number of times, it unlocks the Anvil. Unlocking the Anvil unlocks the new Badge of Justice rewards, and yet another daily quest. If you're itching to make a purchase from Smith Hauthaa, encourage your friends to do this quest as often as they're able.
Aside from unlocking the next step of Quel'Danas, this quest has another reward. Upon completion, you will receive 11 gold, 99 silver, and 250 Shattered Sun Offensive reputation. Once the anvil and Badge of Justice rewards have been unlocked, this quest becomes 'Don't Stop Now...' and retains the same objectives.
