Idea works like this:
-Price of trading energy goes up. Price of items in supply depot goes down to match price of energy.
-Price of trading energy goes down. Price of items in supply depot goes up to match price of energy.
Example: Price of energy is 5,000 crowns per 100 units of E. Current price of 50 Radiants is 700 E.
Price of energy goes up to 10,000 crowns. Price of 50 Radiants drops to 350 E.
-Relative value of energy will be decided by Grey Havens (probably somewhere around 6-7k cr), and Supply Depot prices can be updated weekly.
Energy always costs the same amount. $5 will always net you 1,600 from the purchase tab. However, the crown to energy conversion rates change depending on supply and demand. A change like this would make energy inherently less valuable, sort of ruining the purpose of having it in the first place.
