Magical terrain

Magical terrain is an overlayer that, in most cases, gives bonuses or penalties in combat. It doesn't affect Movement, but uses whatever Terrain is under it for movement cost. It can cover all other terrain types except Rock. While there are only two kinds in Restoration of Erathia and Armageddon's Blade, Shadow of Death increases it to a total of ten.
