Terrain

Terrain represents the different land features and barriers inside expedition maps. Passable terrains deplete sanity to travel across: more difficult or treacherous terrain costs more sanity. Any travel has a start cost of 5 sanity plus the travel costs of each traveled tile. Hovering over terrain reveals its type, and potential routes display their costs when charting course.
