Black Tiger Fangs and Hides
You have 3 different options of which zone you'd like to farm these guys in, Carpenter's Landing, Jungner Forest and Batallia Downs. I prefer Jungner Forest. The Black Tiger Fangs sell for a good 7.5k a stack and Hides sell for 800g each, but aren't stackable. If you're a Thief you can steal Crab Meat from the tigers, almost doubling your income!
