[Maltrease]

You know where that could still be extremely useful is if you are fighting Vanhiem or Heleheim (midly back to topic). It would actually let you see where there troops really are and what kind of forces they are building up.

I wonder if you had a harpy attack a provence the same turn the maenads spawn... one that was repeately shown to have low PD. How high of a PD you could take out? If you could make them raise it to 7+ you could then take it out with small raiding force. That might be troublesome to deal with if they have to focus their main attention elsewhere.
