When you first enter in Dangruf you will see very weak gobs and rabbits, as a while of traveling you should find a geyser that shoots up water, stand over the gyeser to be lifted up. You should now be in an area with Goblin Butchers, Ambushers, and Tinkerer's, along with Wadi Hares, and Giant Grubs. This is where the money making starts. Kill everything you see. You should get these items: Gausebit Grass, Leather Armor Pieces, Hermit's Ring, Zinc Ore, and possibly a Dangruf Chest Key, and Mythril Ore. If you did then look around for the chest, and use you key to open it. You should get about 500+ gil or a Tropical shiled which sells for 900 gil on Sylph in Bastok. If you get Mythril Ore, that sells for about 2,000 gil. You can also obtain Sulfur which sells fairly high for a stack, worms drop it. Now that that is done, go until you find an area with Goblin Leechers, Gamlers, and Muggers. ONLY attack the leechers, sometimes they drop Scrolls of Warp(which sells for like 10k), and Deoderize(which sells for like 1.2k). If you also about level 40 you can kill the NM: Geyser Lizard which will drop Steam Scale Mail which sells for about 20,000 gil. But the NM is level 28-30, and can be found at F-10. Keep doing this until your invintory is full and you'll probably make about 20k worth of assorted things. Below is a price of everything:
Hermit's Ring: 2,000 Gil
Zinc Ore: 200 Gil
Tropical Shield: 900 Gil
Gausebit Grass: 600 Gil
Mythril Ore: 2,200 Gil
Scroll of Deoderize: 1,200 Gil
Scroll of Warp: 10,000 Gil
This is the full list of things that each mob drops, just in case you were wondering. Also hold onto all Animal Glue (All of the tier 2 goblins drop it) and Sulfur (dropped by the Giant Grub), two things which weren't listed. Animal Glue goes for about 2k a stack and Sulfur is about 4k in my server.

As for all of the other Goblins they pretty much drop the same things disregarding the spells. This can also be a good place to farm for lower level people that can kill goblins. The lowest level goblins drop Wild Onions which sell for about 4-5k and sell quickly since they are used in the Meat Mithkabob recipe.
Other notable kills for all levels here are Wadi Leeches which have the possibility to drop Beastmen's Blood which can be used in the Drain quest (The Rumor) in Sandoria or sells for about 2k a piece. All crabs here can be killed for Land Crab Meat which sells for about 3.5-4k a stack. Some of the lizards here can also drop lizard skins which sell for 8-10k.
This has become one of my favorite places to farm because of the simple fact that you really can come here and kill anything (or train everything together and kill them all in one hit in my case), as everything here has decent drops.
If u have a job level 40ish and have thf sub. Go to Dangruf Wadi and train Gob. (train mean that u make monster aggro , u dont attack it yet u continually gather more monster. After u done, KILL THEM!!!!!!!) After u train gob kill them with a weapon skill that can cause dmg within area of effect and watch gil come in quickly..... (*^.^*)
