OK so by now you relize that you are getting a nice amount of exp. and very little gold, and when you level up enough to get that weapon/armor you have been waiting for you dont have the gold. In a nut shell that is what the game is trying to do!!
example monster: 850exp and 200gold
Now you have just leveled up by 850 exp points and you have recieved 2 cents worth of gold. Lets try this; fight monsters that give you equal(=) amounts exp/gold AND lets lower the exp recieved so that you can earn more gold per level How?? funny you should ask...
1. Goto Isle d' oriens
2. First doorway on right (lady tomo and her cat)
3. Click in the trees over her head (strait above)
4. Humidus(cloud)will give you a ride to a flying ship
5. Talk to lady drackel (fight two battles)
6. Humidus will then offer a ride back off the ship (click "Ill stay"
7. click the arrow on screen
8. fight battle
9. after (each battle) arrow right then arrow left battle and arrow right arrow left

OK so what are you going to get for this effort

EVERY BATTLE is the same (lvl 20 monster) 200exp.200gold(no matter how strong you are OR what lvl you are, lvl 5 or lvl 130 fights the lvl 20 monster 200exp200gold

Now watch this math- at lvl 60 you need 40000 exp to reach next lvl if you fight here you will get 40000 exp AND 40000 gold by the next lvl OK now you have trained and become stronger you need 43000 exp for next lvl so fight here get 4300043000 fighting the same lvl 20 monster!!

SO what are you going to buy with your 83000 in gold in two lvls???
