Tough Horse
Use this trick and your king's horse will only take about 10 percent of the damage it normally would in battle. Click on the king and then the icon for him to get on his horse. Click the icon multiple times in rapid succession just before he gets on the horse to activate this cheat.
Fortify the Towers
Pause the game and then direct groups of men to enter a tower. As long as the game is paused you can keep ordering men into a tower, which will allow you to fortify your tower or hide your men from enemies on the ground.
Full Honor Feast
This trick will give you full honor for a feast in less time. The increase in honor will help you unite the kingdom. Click the keep while there is a feast going on in your castle. A button that will allow you to return to the keep will pop up on the screen. Click this button to end the feast yet still get the full honor normally awarded for the feast.
Sleepy Head
This trick is more of an Easter egg in the game than a cheat. Play the game after midnight and you will hear someone ask you, "It's very late sire, shouldn't you be sleeping?"
