Pros:
80% accuracy. When capturing a dwelling (as well as a town), she inflicts paralysis. This makes her 10% more effective than the Banshee in terms of accuracy. Important! The Baroness should move after the opponent. It's not worth attacking the Ogre in the dwelling.
Flight - allows her to move further and faster.
Fear - the fleeing monster takes damage and doesn't dare to retaliate. With a Berserker, Giants, Ogres, and other large monsters can be defeated in 3-4 days if she's alone. Usually, I have two of them to use the following tactic: Remove and place a spellcaster on the same turn. Then, large monsters should beware.
