Action Stage

The Action Stage is the core part of the game turn. The majority of the Action Stage is in the form of Impulses, in which the two factions alternatively are able to perform actions with their respective militaries.

Weather
The player who has the first impulse (not necessarily the player that won the initiative) rolls a die and references the Weather Chart to determine what weather effects affect what weather regions; if the result from the previous weather roll contained one or more asterisks (*), add 1 to the roll for each asterisk.

Reference the Weather Effects table for how each weather effect affects movements, combat, and other aspects of gameplay.
 * A sea box is in the weather region in which its name box resides.

Addition Weather Effects and Terrain Modifications

 * Desert and Desert Mountain hexes treat Blizzard effects as though they were Snow instead, and treat Storm effects as though they were Rain instead. Rain and Snow effects are treated as Fine weather instead.
 * Swamp hexes in Snow or Blizzard are treated as though they were Forest hexes.
 * Lake hexes freeze in Snow and Blizzard. Frozen lake hexes are treated as clear; units on a lake hex when it unfreezes are placed on the production circle to arrive next turn as reinforcements.
 * When Option 8 is in use, Flying boats (and, if using Option 46, their pilots) that are on a lake when it freezes are placed on the production circle to arrive in two turns as reinforcements.


 * Iced-in ports are closed in Snow and Blizzard.
 * Closed ports can not transport resources or build points, and can not be used to trace an overseas supply path.
 * Naval units moving into a closed port must immediately stop and are turned face-down. Naval units in a closed port may not move or reorganize at any time, even during final reorganization.

Turn Length
The result on the weather chart also gives a circled number; if the last impulse test die roll at the end of the impulse doesn't end the turn's impulses, the impulse marker is advanced as many spaces as indicated by this number.

After determining weather effects, move on to Declaring War.
