It’s often worth using your Chancellor for this, but not as your exclusive method of expansion. The chances of success are based on your Chancellor’s diplomacy stat, and with a high enough stat he can even create a claim on a whole duchy if the target holds one.Īlthough this is powerful when it works, the low chance of success and the fact that it’s entirely up to chance makes this a very unreliable method of expanding. Simply tell your Chancellor to sit in a neighbouring province and he’ll have a percentage chance over time to generate you a claim. In my original guide, How to Get Married and Go to War I briefly touched on the ability to fabricate claims on your neighbours.
