Another way to ruin a province, this time using water gems. That's really what the game needs, as there are way too few ways to do that.
What about creating some water spells that actually
build up a province (s population) ?
On the other hand I must agree that your suggestion has a way better chance to acutally find it's way into the game. Seemingly the developers are just to fond of weapons of mass destruction
