Attrition causes armies to take casualties if they move through hostile terrain such as snowy wastes, deep ocean, deserts and swamps. Additionally, corruption and some other factors can cause attrition.
Any attritional effects present in an area on the campaign map can be seen on the tooltip shown when the cursor is held there.
Terrain should not be confused with climate.
