You can "farm" gold by selecting a species of enemy to hunt to collect their gold drop. In the Ascalon area, the biggest gold drop is 20 gold. Try to go to Kryta and hunting the Ettins in the west end for better drops (20 to 80 gold). The best areas are in the Maguma Jungle and Crystal Desert (80 to 130 gold). These areas are tough for most people, and they choose to "run" to the next town/outpost/city instead of fighting. Instead of loosing money from it (most runners ask 500 to 4,000 gold in payment), fight your way there. You will make money and level up fast.
