5.2.1 Determining weather conditions

Weather should play an important part in most adventures. As well as being interesting for fleshing detail into the world in which an adventure is taking place, the weather can affect aspects of the game such as:

• the rate at which characters can travel;
• the chances of certain types of magic succeeding;
• the chances of successfully piloting a boat or ship; and
• the chances of surviving in the wild and foraging for food and water.

The weather is dependent on the type of terrain through which the characters are travelling, the season and whether it is day or night.

Weather is notoriously fickle and weather conditions should be determined afresh each day. Characters may, however, attempt to predict the weather, or control the weather using magic.

The key elements of the weather to be determined are:

• Wind strength;
• Wind direction;
• Humidity; and
• Temperature.
