Note: Favors with non-allied nations decays by a fixed percent per month. If you’re at war with them, all favors are instantly erased.
Method 1: Maintaining an Alliance
By default, you automatically gain favors from your allies each month. The amount is based on your combined allied strength and your contributed portion to that total. Having a stronger military than your ally means you’ll accrue more monthly favors. This simulates the real-life concept of a superpower’s ability to influence weaker nations more frequently.
Method 2: Currying Favors
This is the simplest and most reliable way of gaining favors. You’ll need a diplomat to actively generate favors with your target. To do this: The amount gained depends on your diplomatic reputation, the target’s opinion of you, and your relative military strength.
Method 3: Helping an Ally in War
You gain favors after helping an ally in a defensive or offensive war. The base amount earned is 20 favors — modified by your war contribution. Winning their war doesn’t matter. As long as you’ve made an effort toward their cause, you’ll still gain favors from them. You can increase your war contribution by occupying/liberating forts and fighting battles. Note: For some nebulous reason, you can get more war contribution from battles by losing soldiers.
Method 4: Granting Provinces after a War
When negotiating peace, you can earn favors from either of these two terms: The favors gained here depend on your ally’s war contribution and the war score cost of the provinces that were given. Note: You won’t gain as many favors if you had promised land to your ally at the onset of the war. You’ll actually lose trust if you don’t fulfill this promise.
