Salphaxia Salt Blizzard

If successful, you may designate twelve land hexes on the world map to temporarily become desert terrain for the duration of the entire war. These hexes must be adjacent to at least one other Salt Blizzard hex. Increase the number of hexes you may designate by two for every 5 you exceeded the DC. Increase the cost of Salt Blizzard by one for every hex that is either in another nation's territory, or urban terrain. Additionally, by increasing the cost of this spell by three, you can grant immunity to desert terrain attrition to all domestic units.
