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.

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:

• creatures with Flight, which are not subject to terrain movement costs at all
• Floating creatures, including those floating from the Weightlessness bless
