Quests
Rulers of kingdoms can make rewards available for collection by creating a quest. When you create a quest you must specify the reward, the quest type and the quest target.
The quest reward can be anything that you could sell on the Open Market or an Artifact. The reward needs to be good enough for the attack type and kingdom targeted. This unfortunately is figured out by trial and error. You can only quest up to 40% of what you have so for instance 40% of your archers.
The quest type can be an attack (military, raid, assassination of x, etc...) or a spell. If you specify a spell then you also state the mana and obscurement mana needed to fulfill the quest.
Last of all you need to specify the quest target. It is basically the kingdom that you want the quest type done to. The quest target must be within your attack range and you must have their map.
Quests take 4 - 12 hours before they are available to collect.
