When you are leveling up or killing monsters,you will get some gold falls from monsters,but that is far from enough.Do pick up all
items from every drop.such as stones,equipment.if you sell drops to NPCs,you barely get enought gold to buy potions.but you will
earn more money than selling them to NPC's.escepacially do not sell rare and good items to NPCs.such as Seal of Star,Seal of Moon
and Seal of Sun items.they are very rare and maybe value for Millions.
Next step is to learn prices in the market.Learning prices is useful to moneymaking,which mean once you know prices and master the
stricks,you can gain more profit by buying and reselling.Do not sell items if you don't know the proper price.you can compare the
price with others or just ask around and find the right price.it is always correct to buy them cheaply and sell them at the
average or even higher price.by the way if you badly need gold,you can buy gold either.igvault is a good choice.
