Acquire the reagents Ghak Healtouch needs from the Badlands, then return to him in Thelsamar.
[class], I would make use of your services. I am an alchemist of some note, and I seek your aid in acquiring some reagents found out in the Badlands.
I need the following items to replenish my stocks: five buzzard gizzards, ten crag coyote fangs, and five rock elemental shards. Obviously, you can get them off of the beasties themselves; if you're not the fighting type, then find friends who are.
Acquire these items for me, you'll get some coin out of the deal.
Well, what say ye?
