Environment

Since the party will be spending a lot of time outside, I want to make sure that the environment plays an important part in their adventures. To accomplish this, I am expanding the rules for environment using some of the material from the old AD&D Wilderness Survival Guide.

Temperature

There are two ways to look at temperature. There is the actual temperature. This is the temperature of the air around the characters. Next there is effective temperature. Effective temperature is the actual temperature modified by certain environmental factors such as wind chill. Effective temperature reflects how the temperature feels to the characters. Finally, personal temperature is a reflection of how well the character’s clothing and gear protect him from the environment. Per the tables below, all armor and clothing provide a temperature bonus. Temperature bonuses from clothing and armor stack (but not from two sets of clothing or armor).

Clothing

Clothing in the Core Rulebook and the Advanced Player’s Guide is classified into one of four categories. Excluding Hot clothing, the effectiveness of a higher category can be achieved by wearing twice as much of a lower category (e.g., wearing two layers of cold attire is equivalent to wearing one layer of very cold attire).

Protected and Unprotected Characters

Unprotected characters are effected per the hot and cold danger rules in the Pathfinder Core Rulebook. Whether a character is protected or unprotected depends on the type of clothing that she wears. A character is considered unprotected if any of the following are true:

  • Wearing very cold clothing in an effective temperature higher than 30°F.
  • Wearing cold clothing in an effective temperature lower than 0°F or higher than 50°F.
  • Wearing moderate clothing in an effective temperature lower than 30°F and higher than 80°F.
  • Wearing hot clothing in an effective temperature lower than 50°F.
  • Wearing any metal armor (excluding studded leather) in an effective temperature higher than 80°F, regardless of clothing.

Temperature Effects

Even if a character is not suffering from frostbite or heatstroke, the temperature still exacts a toll. Provided that a character does not have immunity to heat or cold, she suffers penalties to her Strength, Dexterity, and Constitution in addition to a reduction in base movement speed is reduced and a penalty to hit. Casters must also make a concentration check to equal to the absolute value of the penalty plus the spell level.
