I was trying to get the Belt of the Fang for my lvl 20-s Druid, and after much frustration (about 20+ boss kills) and no drop, I decided to craft the Deviate Scale belt, of which I had to farm for the scales. Took me a couple hours to get 10 from drops and skinning, even as a lvl 60. Yes, you can get them in or out of the instance.
