5. Upgrading:

This may not help make the best money guide, but it will help you earn a few sum of ure extremly broke, first way is buy items from the store to upgrade make sure its weakest mage armor or preist.

Why I chose mages and priest is that they sell the fastest and there alot of them in the game.

Buy 10 set of each and upgrade them as far to +7 and sell it for 20m or less

Notice: I Will soon make a Upgrading guide when i have time.
