Apparently alchemists can now get specializations, and engineers are deputized to help in potionmaking. Enchanters get a bunch of new enchants, including a +12 spell damage ring enchant. Judging from the engineering item names, the new metals will be Fel Iron (probably minable near Hellfire Citadel), Khorium, Adamantite and Eternium. There's one thing that caught my eye, though. A portable mailbox. Great, now I have two things I can make for raids.
