Having a Home Kingdom doubles the tribute amount from the Home Kingdom, and serves as a collection spot for all gold and tribute from all Kingdoms.
Players can set a home kingdom by doing the following:
- From the world map, select the kingdom to be made home kingdom
- Select the 'Set as Home Kingdom' button
You can change your Home Kingdom as often as you want for free.
Once you have chosen your Home Kingdom it will have a gold name on the Map and a gold border in the Kingdom pop up menu.
