'''Terrain and Climate''' matters a lot when engaging in a battle and can easily decide wars. It also affect the [[RGO]] output of a province and is often strongly correlating with life rating.
Each [[province]] in the game has a certain terrain, which cannot be altered in any way.

* Defense: Defending armies get this number as a bonus to all combat die rolls.

== Supply Limit ==
Supply Limit determines how many regiments you can have in a province before suffering increased attrition. It is affected by ownership, [[occupation]], terrain and [[Industrial technology]]. Having more troops placed in the province, than the supply limit allows, gives the troops attrition.

=== Modifiers ===
* Infrastructure increases Supply Limit by {{green|3.8}} at 100%. This means level 6 Infrastructure will increase Supply Limit by 0.63.
* Chemistry & Electricity tech tree increases the Supply Limit.

=== Multipliers ===
* A multiplier is applied to the Supply Limit depending on the status of the province. For provinces that you own and control, the multiplier is {{green|x2.5}}.

=== Climate ===
* Harsh Climates give {{red|+5}} Attrition, while Inhospitable Climates give {{red|+10}} Attrition.

=== Attrition ===
Attrition is a loss of troops by wearing down. It is applied if there are more troops in a province than the current Supply limit. The attrition gets exponentially larger, the more the stack goes over the supply limit. Laying siege to a province also give additional {{red|2%}} attrition.
It is applied every month, or when a unit enters a province. Units in battle do not suffer attrition.

Attrition is stated as a percentage of the total stack, which is lost every time it is applied. It is capped at {{red|15%}}
