For extremely easy gil it starts off a bit slow but believe me it gets good.
All you need is a character in Bastok, about 2-2.5k and patience.
First you go spend you money on a stack of Pickaxes (from the NPC) and go mine in Zehurn Mines. You will probably get a few pebbles but your looking for Iron and Zinc ore, on my server they both sell for 1-1.5k each. After you are full of ore (dont drop ANYTHING) or run out of pickaxes run to the AH and sell the ore, be patient dont go cheap jsut to sell let it sell. While your waiting for it to sell go get signet and go fight bees and worms you can then stack the Wind and Earth crystals and sell them also. Finally your ore sells, now make sure you go buy more pickaxes and repeat, when you finally get enough profit go buy Brass Flowerpots from Boytz, continue Mining and Crystal farming. When you have 10 pots, enough gil for pickaxes and some extra go look up Herb seeds on the AH, you want a stack of them, also you will need a stack of water crystals. If you can buy a workbench it would be good (optional). Now go plant them and check them once ever real life day. Finally in about 2-3 rl days you will harvest them, about 75% of the time they will be fire crystals which you can sell on the AH or you can go to the blacksmithing guild and use to make Bronze Ingots (3 copper + 1 tin + fire) soon you will have some gil and you will also be around 9-12, at this time you can either go lvl in Valkrum Dunes ( i suggest) or go play in Palborugh Mines in which you can mine also, though only on the first floor. When your character hits around 25-35 you can begin to mine in Yughott Grotto which will then get you some more valuable ore and there are many places after this. Field gear helps tremendously but its not needed. I suggest taking up Smithing so that you can smelt your ores when your out mining and maybe even Goldsmithing for those zincs and rocks you get later on. if you have any questions send me an email at :
