Resources

Open world resources are the fundamental backbone of the whole kingdom. You'll need them for crafting items such as:
 * Siege weapons
 * Mount armour
 * Unit equipment (weapons, armour)

There are copper, lumber, cloth, iron, leather and stones. Each of them are available in different rarities (level 1 to 3). You can craft higher rarities by transforming some of the lower levels into higher ones (e.g. three lvl 1 lumber into one lvl 2 lumber).

Each resource has to be refined out of raw material. You can gain them through mines, quarries, farms and lumbercamps, which are found in the open world. In exchange for extraction token (gained by daily quests) and some bronze you can gather them there. There are aswell rare gathering points, where you can gain higher rarities. Those raw materials then need to be processed into rare materials. Therefore go to the Unit Refinery Agent and choose the resource of your liking. Dont forget to check the resource piles after the refinement process is done.

Other uses of the resources are to gain money from trading with them or upgrading your camp buildings. Most importantly the cities and villages your kingdom controls will need a lot of resources to grow and increase their level. Except those normal resources there are another kind of materials, which you will need to craft your hero equipment. You either get them as loot by killing bandits in the open world or by buying them from the smuggler, which is an npc, who sells resources for bronce. Those hero resources aswell need to be refined to a certain level. Craft them by going to the hero refinerey agent. There are iron, copper, wood, cloth and leather.
