Well met, <class>. I've something that might interest you.
I have in my possession a set of armor much like the one worn by those of your profession, but of much higher quality. I'd be willing to trade the bracers for ordinary ones in exchange for a small favor.
The blood of the frostsabers and bears that inhabit Winterspring has properties I'm in need of at the moment. Bring me a sizeable sample of it along with the bracers and a small amount of gold. You shall find the effort worth your while.
