Radiation is a deadly threat to those who would explore technological or ruins of advanced civilizations, and even in areas that appear devoid of strange artifacts, the land, the water, or the local flora and fauna may be irradiated. At the GM’s discretion, adventurers may even be affected by the cumulative effects of mild levels of radiation that would be harmless if encountered briefly, but may build into dangerous levels over sustained or repeated periods of exposure. Radiation is a poison effect, but its secondary effect is different from its initial effect. Radiation dangers have four levels of intensity: low, medium, high, and severe.

Area of Effect: Radiation suffuses a spherical area of effect that can extend into solid objects. The closer one gets to the center of an area of radiation, the stronger the radiation effect becomes. Radiation entries list the maximum level of radiation in an area, as well as the radius out to which this radiation level applies. Each increment up to an equal length beyond that radius degrades the radiation strength by one level. For example, a spherical area of high radiation with a radius of 20 feet creates a zone of medium radiation 21 feet to 40 feet from the center in all directions, and a similar zone of low radiation from 41 to 60 feet.

Initial Effect: Radiation initially deals Constitution drain unless the exposed character succeeds at a Fortitude saving throw. A new saving throw must be attempted to resist radiation’s initial damage each round a victim remains exposed to it.

Secondary Effect: Secondary effects from radiation deal Strength damage at a much slower rate than most poisons. This secondary effect ends only after a character succeeds at two Fortitude saving throws to resist secondary radiation damage. If a character is suffering Strength damage equal to her current Strength score, any further damage dealt by secondary radiation is instead Constitution damage.

Mutation In some settings exposure to radiation can cause mutations rather than Str damage. A character who does not posses the Helix integrity racial quality have a 25% of gaining the Mutant template instead of taking ability damage when exposed to High or Severe levels of radiation.

Removing Radiation Effects: All radiation damage is a poison effect, and as such can be removed with any effect that neutralizes poison. Ability damage and drain caused by radiation damage can be healed normally.
