Atmospheres

An atmosphere is a layer of gases held in place by a planet’s gravity. There are various other types of atmospheres that are hazardous to most creatures.

NORMAL ATMOSPHERE

This atmosphere is made up of gases such as oxygen and nitrogen that most creatures can safely breathe. Planets with normal atmospheres have weather patterns that vary depending on climate. Planets such as Castrovel and Verces have normal atmospheres. Artificial atmospheres, like the one on Absalom Station, are usually normal.

CORROSIVE ATMOSPHERE

A corrosive atmosphere is made of caustic gases and creates dangerous weather patterns, such as acid rain. A corrosive atmosphere deals minor to moderate acid damage per minute to creatures and objects. Certain metals and treated materials might resist a specific type of corrosive atmosphere.

THICK ATMOSPHERE

A thick atmosphere has high air pressure. Breathing a thick atmosphere usually requires characters to attempt a Fortitude save every hour to avoid becoming sickened until they begin

breathing normal air. The value of the sickened condition

depends on the specific atmosphere (typically sickened 1).
