Once you’ve got a character of high enough level, head to Winterspring in search of a bunch of great potential spots to farm your gold.
1. Lake Kel’Theril (53.42) is a frozen lake in the center of Winterspring. The shores of the lake are home to the Ruins of Kel’Theril, which along with the lake itself are populated by many tormented spirits of the Highborne. These souls are level 54 and 55 ghosts that are relatively weak, drop up to 8 silver coins and also have a chance to drop green items and, if you are lucky, some epic item. For more fun, chests also appear (randomly?) In this area, and every week the entire lake is invaded by water elementals commanded by Princess Tempestria. You can do quite well just killing the elementals and selling their ‘Essence of Water’ drops, but if you’re up to the task (recommended by the group), kill the princess and help yourself to the blue items she tends to drop. The invasion lasts until the princess is killed.
Heading southeast from the lake to (57.50) you will find a bunch of cobalt dragons (56-58 elites) around a cave. Killing the little dragons (Wyrmkins, scalebanes and mageweavers) has a small chance to drop a ‘Mature Blue Dragon Sinew’. This is being sold to the highest bidder, and trust me they will bid as it is a very difficult item to obtain and necessary for a high level hunter quest.
2. Everlook is a trading post run by the goblins of the Steamwheedle Cartel. It is located at the crossroads of the main commercial routes of Cuna del Invierno. Head north and east to (67.40) and you’ll find an excellent area to farm Ice Thistle Yetis. In addition to throwing out vendor junk items and sometimes blue items, you can also skin them for sturdy, thick leather that consistently sells well.
3. Dark Whisper Gorge.
In addition to attacking the Frostmaul giants who have a 1/50 chance of dropping a ‘Greater Frost Protection Potion Recipe’, you can travel up to (60.75) and try your luck against some elite level 60 demons (grouping is HIGHLY recommended). You’ll get a bunch of Felcloth and Runecloth drops, as well as green items. There is a 1 in 50 chance of obtaining ‘Eye of Shadow’ which can be sold for several hundred gold coins.
Between these three locations you should be rolling in gold in no time!
