The Dynamic Economy System allows the trade and currency values of the world to be altered by the present state of politics. Each kingdom has a currency, as well as a rank in overall prosperity. The rank in prosperity determines the price of items inside that city, as well as the trade value of that nation's currency.

1st - 25% item cost, 400% currency value in other countries
2nd - 50% item cost, 200% currency value in other countries
3rd - 100% item cost, 100% currency value in other countries
4th - 150% item cost, 75% currency value in other countries
5th - 200% item cost, 50% currency value in other countries
6th - 300% item cost, 20% currency value in other countries

Also, item types are divided into certain categories. The more items of one category a merchant in the city buys, the lower items of that type will cost (within certain limits) Likewise, the more of a kind are bought, the more items of the type cost.

Note: only generic items are affected by this system. Rare items are made by players and can be gotten from the auction system.
