This chapter provides additional information for the game moderator, such as the movement capabilities of creates with attributes far beyond human limits, the mass of commonplace objects, and the speed of various creatures and vehicles.

Hostile Environments

Table: Hostile environments
Environment Effect
Darkness Attack and defense penalties
Dehydration Maximum Endurance reduced, once per day; -3 penalty on all tasks
Exhaustion Cumulative penalties
Exposure Maximum Endurance reduced, from once per hour to once per six hours
Falling Lose one Endurance for each five meters fallen
Fire Damage depends on heat and intensity, once per round
Poisons Maximum Endurance reduced, from once per round to once per hour
Pressure Maximum Endurance reduced, from once per round to once per minute
Starvation Maximum Endurance reduced, once per week; -3 penalty on all tasks
Suffocation Maximum Endurance reduced, once per minute


Darkness

Darkness, fog, rain, blizzards, and other visual impediments can make combat much more difficult. If an attacker can't see the defender, the attacker incurs a -3 penalty. Conversely, if a defender can't see the attacker, the defender incurs a -3 penalty.

A character with the appropriate powers, or equipment permitting them to perceive normally, suffers no ill effects from darkness.

Dehydration

A character who goes more than 24 hours without drinking begins to suffer the effects of dehydration. Initially, the character experiences headaches, loss of appetite, and dry skin, followed by rapid heart rates, elevated body temperatures, and fatigue. After three days without water, the character experiences tiredness, irritability, and dizziness. Severe dehydration results in death.

If a character is suffering from dehydration, their maximum Endurance is reduced by one per day until they are rehydrated or until their maximum Endurance is reduced to zero. Additionally, the character incurs a -3 penalty on all rolls. Once the character is rehydrated, their maximum Endurance is restored at the same rate it was lost.

Exhaustion

Most people need to rest after eight hours of strenuous activity. If they do not, they suffer a -3 penalty on all skill rolls until they do. If they go more than 24 hours without sleep, they suffer another -3 penalty until they get a solid night's rest.

Exposure

Extremes of heat and cold can be dangerous to those without adequate protection. If a character is exposed to extreme temperatures, their maximum Endurance will be gradually reduced until they find shelter or until their maximum Endurance is reduced to zero. How quickly their maximum Endurance is reduced depends on the severity of the conditions. A hot summer day without shade or water, or a frosty winter night without a coat, would reduce their maximum Endurance by one every six hours or so: brutal, but not immediately life-threatening. If the same character were in a blazing hot desert or in the middle of a blizzard, their maximum Endurance would be reduced by one every hour. Once the character is no longer exposed to the extreme temperatures, their maximum Endurance is restored at the same rate it was lost.

Falling

Falling is treated as a normal attack which inflicts Endurance damage. The power level (PL) of a fall depends on the distance fallen: +1 PL for each five meters fallen (rounded in the character's favour), up to a maximum of PL 20. Particularly soft or yielding surfaces can reduce the power level of the fall by as much as half.

Fire

Fire is treated as a normal attack which inflicts Endurance damage. The power level (PL) of a fire depends on its heat and intensity.


Table: Fire
Fire PL
Campfire, torch 12
Burning building 15
Molten lava 18


Very cool and very hot fires are outside of this range. A lit cigarette can cause painful burns, for example, but it's less damaging than PL 12. On the other hand, the Earth's core is far beyond even PL 21.

Poisons

Poisons and pathogens are substances which disrupt biological processes when a sufficient quantity is absorbed by an organism. Described here is a generic poison: your character may encounter poisons or pathogens which are more complicated than this example.

Immediately after exposure, a poisoned character must make a moderately difficult (DV 12) Survival (Brawn) roll against the poison. If the target has Alteration Resistance, they add +3 to their roll. If the Survival (Brawn) roll is successful, the character takes no damage from the poison and suffers only incidental side-effects such as nausea. If the Survival (Brawn) roll is not successful, the character has succumbed to the poison, and their maximum Endurance is reduced by one. Periodically thereafter, the character must attempt another Survival (Brawn) roll (once a round for very potent poisons, once an hour for very weak poisons, and once a minute for normal poisons, at the GM's discretion). Each failed Survival (Brawn) roll results in another reduction of the character's maximum Endurance. This continues until the character successfully makes a Survival (Brawn) roll, or they are administered the appropriate antidote (if one exists), or their maximum Endurance is reduced to zero. Once the character successfully makes a Survival (Brawn) roll against the poison or is administered the appropriate antidote, their maximum Endurance is restored at the same rate it was lost.

Some poisons and pathogens have additional effects, such as blindness or paralysis.

Pressure

If a character is exposed to extreme atmospheric pressure, their maximum Endurance will be gradually reduced until they return to their natural atmosphere, or until their maximum Endurance is reduced to zero. How quickly their maximum Endurance is reduced depends on how prepared they are and the severity of the conditions. If a trained diver were 30 meters under water (approximately 3 atmospheres, or 30 decibars), their maximum Endurance would be reduced by one maximum Endurance per minute: life threatening, but not immediately fatal. If the same character were 300 meters under water (approximately 30 atmospheres, or 300 decibars), their maximum Endurance would be reduced by one maximum Endurance per round. Once the character has returned to their natural atmosphere, their maximum Endurance is restored at the same rate it was lost.

A character with Environmental Immunity is unaffected by high pressure.

Starvation

A character who goes more than 7 days without eating begins to suffer the effects of starvation. Initially, the character experiences weakness, confusion, and irritability. After three weeks without food, the character experiences hallucinations and convulsions. Starvation eventually results in death.

Each 7 days a character goes without eating, their maximum Endurance is reduced by one, until their maximum Endurance equals zero. Additionally, the character incurs a -3 penalty on all rolls. Once the character has resumed a normal diet, their maximum Endurance is restored at the same rate it was lost.

Suffocation

If a character needs to breath but is unable to do so, such as someone drowning or suffocating, their maximum Endurance is reduced by one per minute until they can breathe freely again, or until their maximum Endurance equals zero. Once the character is able to breathe normally, their maximum Endurance is restored at the same rate it was lost.
