Alright, this is an overview of the DI Economy. There are going to be three parts to this:

Summary
Making and Spending Gold
Selling Items

Alright, without further ado, let's get started with:

Summary
What is an economy, you ask? Good question. An economy is a system by which goods and services are exchanged. These exchanges typically involve monetary compensation.

In layman's terms, it's how you buy stuff.

In DI, the economy functions much like a normal one would. You supply a service [fighting] to someone, and in turn they provide you with monetary compensation[skill/special and gold]. No one really knows exactly to whom you are providing the service, but for these purposes we'll call it the government (The mods). You can then invest the monetary compensation that you recieved in equipment that will help you to provide the service more efficiently [you will be able to defeat your opponents more easily], and secure your paychecks, which you can then invest further to secure more paychecks, etc.

So, that's the basic summary of the economy system.

Now let's look at the specific ways in which you make and spend gold:

Making and Spending Gold

Now, as we stated earlier, you make gold by winning battles, primarily. There will be the occasional time where you can make gold in other ways, but for now just think battles. So, when you win a battle, you have to do something with the gold, or else it will simply sit in your character's inventory and do nothing. Unfortunately there are no banks or stock markets in DI, so your gold will not increase unless you earn more. That being said, you don't have to spend your money after every battle. You can save up to buy better items, since better items cost more money than weak ones and are generally worth the wait.

Now, in order to spend money, you need to buy an item. So, the first thing you must do is pick an item that you wish to buy. Try to pick one that will go well with your class. Mages should not use heavy armor most likely, and warriors can probably find a better weapon than a dagger wand.

But wait! There is one more thing you got from that battle, isn't there? Yes, that skill/special, which varied in strength depending on how long and well-written your battle was. Well, this one is easy. Just decide what type you want it to be, either a spell or skill if you are a caster, or a special or a skill if you are a warrior class. Once that's done, come up with an idea for what you want it to be, and ask a mod for approval. The mod will tell you if it is okay or not. If it is acceptable then post your new skill/special on your character page.

So, what do you do if you have an awesome character who has outgrown his items? Stay tuned to find out.

Selling Items

When you want to sell one of the items in your inventory, you have two options:

One option is to simply sell it back to the "shop" for 50% of what you paid for it, rounded down if there is a decimal place. (So any 11 gold item would sellback for 5 gold)

The second option is to sell it on the DI Marketplace. This option will probably take more time since there are not too many buyers in the market, but you will get more money back. However, when you sell in the Marketplace you should have the cheapest price, so anyone looking for that particular item will buy from you instead of the store.

Basically, sell to the shop if you need the gold ASAP, but if you aren't in a rush to get the gold you might want to try the marketplace.

Loans

You can loan up to 10 gold. But...Whenever you loan gold, and subsequently spend it, you can?t buy any other items until you repay your loan. And a 50% interest is added, rounded up. So if you loan 10 gold, you?ll have to repay 15. If you loan 1 gold, you repay 2.

So, there you have it, the DI Economy in a nutshell. Hope you enjoyed it.
