[Master Shake]

When you right click on a unit in battle, a window comes up with that unit's stats. You can right-click (I think) on both the number, and the the state name.

For example, it might say Morale: 12.

If you click on the 12, you get a summary of all of the factors geeting you to 12 (base morale, friendly domain, home province, bless, starving, etc.) This is very useful for seeing the exact effects of spells like antimagic (+4 MR if I remember).

If you click on "Morale," you get a pretty good explanation of how Morale works.
