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.

Water:

- Can be traveled over with Water Walk and Fly spells, or by wearing Boots of Levitation or Angel Wings – hero's movement must end on dry land.
- It should be noted that shroud on the water between two squares of dry land does not prevent hero from walking or flying across it and mapping the shrouded area. However, the hero must be able to see both land squares before starting the trip.
- Almost all adventure map objects that are normally placed on dry land can be also be placed on water square and still function normally. The exceptions are Towns, Subterranean Gates and Monoliths, which can not function if visited with a boat.
- The speed of the creatures in the hero's army does not affect movement in a boat, unlike movement on land.
