Multiplier bonuses like Fertility Rites thus applies to the sum of the City income and the Flat bonuses. ( Base income + Structure income + Flat bonuses) x (1 + Multiplier bonuses) x (1 + Happiness modifier) x (1 + Production modifier) x (1 + Enemy at the gate malus) As a consequence, some bonus apply only to some incomes, and not to all. The calculation is made in a specific order. Gives an additional -1/6 income Enemy At The Gate malus.Enemy at the gate: see City Happiness Modifiers's Enemy At The Gate modifier.Production choices provide a Production modifier, see below Producing Gold, Producing Mana, Producing Knowledge.Does only apply to City Income and flat bonuses - Multiplier bonuses like Expansionism or Fertility Rites get neglected.Provides a Happiness modifier, see Happiness.Multiplier bonuses such as +10%, +20%, etc.Structure income: income from the explored structures in domain.The incomes is sub-divided in several components as follow: This will result in a maximum Domain Radius of 9, which can only be exceeded by the Warlord, with the Authority of the Sword spell, for a Domain Radius of 10.Īll city incomes are calculated following the same model.

The following three buildings will each increase the Domain Radius by 1: These three factors grow in the following manner:Īside from growing your city, there are a few other methods to increase your domain. For each level gained, a city will produce a higher Gold income, receive higher Production, and it will increase it's domain radius, allowing the city to cover more treasure sites. There are five levels a city can have, from the smallest, Outpost, through Village, Town, City, and the biggest, Metropolis. The gold income, the production and the domain are dependent on the City Size. Note that Dwellings may benefit from Production and Happiness, but not Population. A treasure site outside your domain will never give any bonus to you.įorts also project domain, but cannot benefit from treasure sites producing Production, Happiness or Population, since they are merely military structures, without a population. These can be bonuses to Gold, Mana, Knowledge or Production, or even increase the city's Happiness and Population. Only explored, unoccupied treasure sites inside your domain will generate resources (hence occupation by hostile independent or faction armies will deprive the city of that resource). Cities have an inherent amount of Gold and Production they generate, and they will project Domain, allowing you to harvest resources from the Treasure Sites around your cities. Most resources are gained as income from your Cities.
