There are a lot of treasure chests that spawn all over the place

At level 36 you will want Shaiya gold to go to Desolace, grab all the kill quests that have to do with nagas and then go swimming to the little island at the northwest corner and kill the nagas.

Be careful though, you will want to watch out for the elite giant that wonders around in the area. Don't worry he only comes ever so often and is extremely easy to avoid。

Level 38-39, go to the Badlands and start grinding on EVERYTHING there. All the creatures are really close together and it is an excellent skinning area. At level 40 go to the Lethlor Ravine and start grinding on the whelps you find there.

You can also skin these and you might get lucky and see a Tiny Black Whelping drop which usually sells on the Auction House for around 75-100 gold depending on the server.

At level 45 go south along the coast into the pirate cove and grind there until level 49. There are a lot of treasure chests that spawn all over the place here so you can make a lot of gold here too. Don't forget to get the kill quests for this place.
