I'm playing my first barbarian campaign (Germania). Does anyone know exactly what the effect of the screaming women is? I suspect it lowers morale of enemies, but wondering if it affects your own troops in some way. I was also wondering if anyone had figured out how close the screaming women need to be to the combat to have an effect.

Another question: What's the trick to using warcry? Does it matter how much time you give your soldiers to yell before charging?

Any advice on proper use of these special abilities is appreciated.
