Our Mount And Blade 2 Bannerlord guide will help you step-by-step on how to become a Vassal as it comes with a lot of privileges and also, penalties.
How To Become A Vassal
In order to become a Vassal, players first need to become a mercenary. To become a mercenary, find a lord and offer him to become a mercenary for him. While you’ll be fighting for the kingdom but, you aren’t part of that kingdom yet.
As you gain more popularity or renown, people will start to notice. After raising your influence significantly, go to the castle and talk to the lord and tell him you want to become a Vassal.
The lord will then direct you to the faction leader whom you have to find. However, if the faction leader is out on a war, it’ll be difficult to locate him because the faction leader will move often. When you find him, tell him you want to become a Vassal.
He’ll only accept the player as a Vassal if they have done enough for the kingdom. Once you become a Vassal, things will change a bit.
Vassal isn’t an ordinary mercenary and hence leaving the kingdom will have higher penalties. However, as a Vassal the player can own land, raise armies for the kingdom, and use their influence to propose votes.
