Modifier list

For an explanation of the game mechanic, see Modifiers. For an introduction into modding modifiers, see Modifier modding.

A modifier is a value that affects various attributes of a country or province.

Overview[edit | edit source]

All modifiers are sorted into one of two internal scopes: country and province. Adding country modifiers to a province scope will not work, and vice versa.

All modifiers stack additively. For example, if you apply infantry_cost = 0.1 and then apply infantry_cost = 0.3, the country will have infantry_cost = 0.4.

However, the effect the modifier value has on its base value can be additive or multiplicative. For example: army_tradition = 1 adds the value to the base Army Tradition, whereas infantry_cost = 0.1 multiplies the base value by the modifier value.

The following examples are mostly positive(green text in game) effects.
