Hey people,
Dealer Najeeb
Was checking this vendor in Stormspire the other day on my warrior and i noticed he was selling a Hardened Adamantite Tube for 12g, which is quite abit lower than what the mats would cost to make that. Anyway, this guy also sells motes, which altough are on a high respawn timer, if you're checking him every now and then for the tubes/mats, you'll find some.
Now for the engineering part, he is constantly selling Fel Iron Bolts + Elemental Blasting Powder. Though these don't sell for alot, they can help get the base mats for leveling 300+. He also sells Adamantite Frames as Irru mentioned in a later post which can easily be resold on AH or saved for when you need them.
He also has a mate further down calledDealer Sadaqat Who is selling Super mana/healing potions, some herbs and other potions.
A handy tip, if you have Dimensional Ripper - Area 52
whenever you use it, just fly up to stormspire and check the vendors, sometimes it is well worth it.
Worth saving the hardened tubes for your goggles when you need them. If you're level 60+ and thinking of starting engineering its a good idea to buy some Bolts/blasting powder and stock them up till you're 300+.
Hope this helps a few of ya. From what people are saying on Wowhead there is a high respawn on the motes.
