AI charter buying

[inspiratieloos]

Can someone explain me what the factors are when a AI buys a charter?
I have seen snakes buy charters and turn into wolves. Same for pigs
I have seen this when
-the wolf was steward
-the snake was steward
-the snake had most citys in that parish
-the wolf had most citys in that parish
-there was an invasion and without invasion
-combinations from above

So can someone please explain how you can get the snake or pig more citys into a parish

the easiest and surest way to get the snake or pig (or rat n wolf for that matter) to buy more charters n a parish is for the snake or pig to already have a lot of villages in that parish.

you can't thin the ai out too much in a parish if u want them to dominate it.

But How can a single wolf in a snake controlled parish, charter bought by a snake, and a lot of snake villages expand?
