Advance Wars: Days of Ruin/Weather

There are four weather conditions that can affect the battlefield that you are playing on.


 * Normal: The standard weather, has no special effects.
 * Rain: No matter if fog of war is on or not, the entire battlefield is covered in fog of war. Not only that, all units have a vision range of just 1 and all bases have no vision around them. Fog of war conditions apply.
 * Sandstorm: Reduces the attack for all units by 30%.
 * Snow: All units have -1 mobility.

CO Penny / Lili / Roumi 's CO effect is all to do about the weather. All her units are unaffected by the weather and her CO power will randomly change the weather conditions for 3 days. CO Lin / Rin can use her CO power to see through the rain.

There are four different map terrains:
 * Normal
 * Desert
 * Snow
 * Wasteland

Despite their name, do do not have any special effects and merely change the look of the map you are on.
