Terrain

Once you know your ideal daily
mileage, modify it for terrain as fol-
lows:
Very Bad: Deep snow, dense forest,
jungle, mountains, soft sand, or
swamp. ¥0.20.
Bad: Broken ground (including
streams), forest, or steep hills. ¥0.50.
Average: Light forest or rolling hills
¥1.00.
Good: Hard-packed desert or level
plains. ¥1.25.
When these rules result in different speeds for
different members of a party, the party must either
move at the speed of its slowest member or split up.
