A creature with Snow Move ignores the movement penalty that snow imposes in cold provinces.
The cost of crossing a province border is the sum of two half-steps, one for leaving the first province and one for entering the second. See map-movement for the wider system. A snow-covered province makes both of its own half-steps 1 point more expensive, and Snow Move removes that penalty.
The saving therefore depends on how many of the two provinces are snowed in.
| Move | Extra cost without Snow Move |
|---|---|
| Between two cold provinces | 2 points |
| Between a cold province and a warm one | 1 point |
| Between two warm provinces | none |
A province is snow-covered whenever its temperature is cold, however that cold arose. Sea provinces and cave provinces never count as snow-covered, so the penalty does not apply to them at any temperature.
The penalty is applied before roads are taken into account, and a road makes the finished half-step cost 2 points lower, so a road can absorb part or all of it.
Snow Move is not the only way to escape the penalty. It is also never paid by:
