Bring 5 Uncracked Scarab Shells to Tran'rek in Gadgetzan.
The scarabs of Tanaris have very hard shells! Hard enough to use as a building material for lots of things. So many things!
In fact, those shells are so useful... the scarabs were hunted all to near extinction!
I know where there are more scarabs, and if you promise to bring me their shells then I'll tell you where they are. Promise?
Ok, the scarabs have a colony in Zul'Farrak. I guess the trolls don't hunt them for their shells.
But you can! Go to Zul'Farrak and get me uncracked shells!
