There you can do two things, either farm for Rugged Leather off all the beasts there.
Or my favorite the Devilsaur-with the Devilsaur you can sell here skin in stacks of 10 and make a large sum of money.
Usually I can sell a stack of 10 for about 30-40g and it takes me an hour to an hour and a half.
