I see that you can turn soil into other terrain with worse move speed, which is cool. However, is there some kind of way to make pits that cannot be stood on? I have a keep inside of my village to fall back to in dire raids. In combat sims, I noticed that raiders will get right up to my embrasures on the keep's walls, nullifying a lot of their defensive value. Are the moats intended to create areas where pawns can not stand? It would be very nice if I could stop raiders from turning my embrasures against me.
