[1] Hexside limits apply to units entering battle hexes. Heroes and fliers ignore limits.
[2] Only mountain folk and fliers may occupy mountain hexes without roads or rivers.
[3] Mountain hexsides are impassible. Exceptions: mountain folk, fliers, heroes.
[4] River hexsides are Uncrossable to most ground units. Exceptions: amphibians, heroes, fliers. Aquatics and amphibians may move along rivers.
[5] Land and sea parts are treated separately. For land hexsides, the dominant terrain (not center) applies.
