*These assume the player characters find a route around the obstacle. Alternatively, the DM can require the characters to scale or span the obstacle, playing out this encounter.

**These extremes must be in excess of the norm expected of the character or creature. Thus, a camel is relatively unaffected by the scorching heat of a desert and a yak barely notices the cold of high mountains.

***This cost is negated by the presence of a bridge or ford.
