There are three main types of Resources in the game - Food, Gold, and Iron.You need them to construct buildings, discover Lost Arts and produce Units.The amount of Gold and Iron you can gain per hour depends on the number of fields you have for these Resources.
Usage and Acquisition
To gain more Resources, construct and upgrade Townhouses and Mines and resource related buildings - such as the Forge and Dungeons.
The amount of Gold and Iron you can store is limited by your Warehouse capacity. Upgrade your Warehouse to store more Resources.
Food is collected from Farms. Build and upgrade your Farms and the Spring of Life to increase the rate at which you collect Food.
The amount of Food you can store in your Castle is limited by the capacity of your Barns. Make sure you upgrade your Barn at the same rate at which you increase your Food revenue or anything over your capacity will go to waste. (The same goes for your Warehouse).
You also need Food to maintain your Units. Every military Unit in the game consumes its own set level of Food per hour. You can exchange excess Resources or Food at the Market for Resources or Food you're low on. Your Friends and Allies can also gift them to you - or you can steal them from other Castles during Raids.
You can use Sapphires to temporarily boost your Resource production for 3 days by 25% (see the "Sapphires" section for more). There are also special Relics which can improve the production statistics of your Castle (see the "Relics" section for more details).
If you have discovered all Lost Arts that do not require Soulstones, you will receive a boost to your Gold and Iron production. Your boost will begin the day after you have discovered all Lost Arts. Once a new Lost Art appears, your Boost will be placed on hold until you discover the new Lost Art; in which case the boost will begin once again.
Sapphires give you extra advantages in the game. You can:
- Get a 3-day boost to your Gold, Iron or Food production by 25%
- Boost the rate of your building construction, reduce the time needed to discover Lost Arts, and speed your Unit production.
- They allow you to produce Imperial Units.
- Purchase Fortifications, Improvements, and exclusive Units
- Expand your Castle
