A setting That randomly generates deadly territories to move from or to.
It could be made to generate a fixed set of territs based on individual map that would automatically turn Neutral if a player either attacks from or to said territ. Could also Work on reinforcement if a player moves to or from a territ that was mined all troops that moved to the territ would be gone. IN the attacking aspect it would need to work like a failed Auto dice battles so that all troops from attacking territ that could have potentially moved to mined territ are lost and in defending or reinforcements aspect mined territs become neutral as a result of any activity.
Another Potentially defining Gameplay option that invites new Strategy for all that play it.
