Ok, to make some money for all of you free players that are level 5 or higher with about 300 hp. First make room in your inventory and buy some food, like 10 withered apple. Then go to the entrance to the goblin cave but do not go in and kill the monsters. Instead go in the goblin cave and come out and kill the monsters outside of the goblin caves. Doing this repeatedly, my character gained 250 gold in less than 30 minutes. Also, if you are a level between 15 and 20 please do not horde this spot. This is for level 5-15 people.
