Terrain

Terrain typically refers to one of the eight basic land types, which are grass, dirt, lava, subterranean, rough, sand, snow or swamp. Water and rock may also be considered as one of the basic terrains, although they cannot be traveled on by ordinary means. Traveling on water requires a boat, while rock is impassable. In addition to basic terrain types, there are several types of magical terrains, which can cover basic terrains providing additional features. Magical terrains typically affect combat or spellcasting, with the exception of favorable winds, which increases movement over water if the hero has Navigation secondary skill.
