This is a sneaky good way of reducing the army size of a kingdom you are planning to fight as this doesn't damage relationships with anyone since you are simply coming to the aid of a 'friend'. Join their fights: If you see a lord in a fight, doesn't matter against what (other factions, bandits, etc), just join the fight on their side for a boost (assuming you win). This will improve your relationship with the lord and the faction they belong to. If you go find the castle they are imprisoned at, break them out of jail (walk around town/castle, find the jailer, pick a fight with them, then go into the jail and break the lord out, finally kill all guards to escape).
Rescue them: Often, faction lords tend to get captured.
Then just let time pass and your relationship with the target faction will be bumped a few points. If you are the king of a faction, there are multiple ways to improve relationships.īribe them: The first is the easiest but costly, talk to your minister and choose to send a faction a gift.
