How to increase domain limit ?

[imba.arrow]

I had played in CK2 with unlimited domain limits. Is there any way to increase domain limit (cheats,system config etc.).

You can try to increase your stewardship/ marrying a spouse with high stewardship and putting them on manage domain task or trying to get your heir to have high stewardship. You can also take the life focus called domain focus in stewardship and level up Architect to get a +2 to your domain limit.

edit- Every 5 points in stewardship increases your domain limit by 1. Increasing your top rank can also increase your domain limit. +1 for being a count, 2+ for being a Duke, 3+ for being a King, +4 for being an Emperor

Your ruler is certain to die so I wouldn't worry about it overly much...

The tier 5 Law dynasty perk gives a permanent +1 domain though.
