Environmental Hazards

Falling: A creature or object of roughly human density falls 900 meters per round. Falling 2 meters or more deals 1d8-1 Physical damage with a Demolition of 0. The damage increases by 2 and the Demolition increases by 1 for every doubling in distance, to a maximum of 1d8+13 with 7 Demolition at 256 meters fallen. Damage taken is adjusted by a weight-dependent modifier from the table below: this change is applied after the maximum. Soft surfaces like sand or grass reduce the damage by 1, very soft surfaces like hay bales or bushes reduce the damage by 2, and sharp objects like spikes increase the damage by 2. Falling creatures and objects also damage whatever they land on, and use an accuracy of +0 to hit creatures in their path rather than the ground below those creatures.

Table: Fall Damage Modifier by Weight

Weight Damage Modifier Demolition
Less than 1 kilogram -6 -3
1-10 kilograms -4 -2
11-40 kilograms -2 -1
41-200 kilograms +0 0
201-1000 kilograms +2 1
1001-5000 kilograms +4 2
5001-25000 kilograms +6 3
25001 or more kilograms +8 4

Light Wind: Light wind interferes with projectiles, causing penalties to attack rolls.

Strong Wind: Strong wind interferes with projectiles, causing penalties to attack rolls. It also flings creatures in the area 5 meters at the beginnings of their turns unless they succeed on a DC 10 Strongman check. Flying creatures are flung 10 meters, which is reduced to 5 meters on a DC 10 Strongman check. Strong Wind also gives creatures in the area a -3 penalty to Agility checks.

Heavy Rain: Heavy rain grants concealment to any creature that is more than 10 meters away from its observer or attacker, and creates sufficient sound to count as significant ambient noise for Auditory Stealth.

Hail: Hail functions as Heavy Rain, but also deals 1d6-2 Physical damage to each creature and unattended object at the beginning of its turn. Damage increases to 1d6-1 for more severe hail.

Lightning Storm: Each round, 1d6-4 (minimum 0) lightning bolts strike beneath the thundercloud. Each lightning bolt picks a random 5 meter wide cylinder beneath the cloud, and strikes the highest creature or unattended object in that cylinder, for an attack with a +5 Accuracy and 1d6+3 Electricity damage; wounded targets are stunned for 1 round.

Lava: Anything that touches lava is lit on fire, and a creature that spends any part of its turn partly or fully immersed in lava takes 1d6+4 points of Heat damage.

Toxic Waste: Toxic waste is swum through rather than walked on. Anything that touches toxic waste takes 1d6 Acid damage, and a creature that spends any part of its turn partly or fully immersed in toxic waste takes 1d6+3 points of Acid damage instead.

Toxic Fumes: At the end of each creature's turn, if that creature has toxic fumes in its lungs, it takes 1d6+2 Acid damage. If the creature (or an object) is merely surrounded by the fumes, it takes only 1d6-2 Acid damage instead. Completely exhaling all air from one's lungs removes the toxic fumes.

Extreme Temperature: Extremely hot or cold atmospheres or metal surfaces are unpleasant to touch. At 100° C, the atmosphere or surface deals 1d6-2 Heat damage per round. This increases by 1 damage for every 50 additional degrees.

At -20° C, the atmosphere or surface deals 1d6-2 Cold damage per round. This increases by 1 damage for every 50 fewer degrees.

Vacuum: Extremely low pressure environments are low on friction, and breathability. Any creature that ends its turn holding its breath with more than one-tenth of its total number of rounds remaining in a vacuum takes 1d6+2 Noise damage. Projectiles can travel unlimited distances in a vacuum: unless a projectile speed is specified they travel 8 times their maximum range per round.

Decompression: Going from a higher-pressure area to a lower-pressure one during the course of a single round can be quite dangerous. If a character goes down one atmosphere very rapidly (as by opening a relatively small room to the outside, or teleporting from an area with one pressure or another), they take 1d6-1 Noise damage, with a +2 bonus to damage for every additional atmosphere of change. If the change is more gradual over the course of the round, the damage is decreased to 1d6-2, +1 for every additional atmosphere.



Sometimes, people may wish to destroy objects. Objects have an AD of 3, unless otherwise noted. Attacking an object or series of objects typically destroys approximately a 2x2 meter square of it (unless it's an area of effect attack, in which case it destroys the touched regions, or a Piercing attack, in which case it destroys a 6x6 centimeter hole), with depth depending on the damage dealt: every point of damage it takes to wound an obstacle is subtracted from the current damage of the attack (only one damage roll is made, no matter how many layers there are). If the remaining damage is insufficient to inflict another wound, the attack stops there.

However, if the Demolition was 2-3, only half as much damage is subtracted from the current damage; if 4-5, only a quarter; and for every 2 additional points of Demolition, the subtraction is halved again. Also, Piercing weapons quarter the subtraction further.

The Demolition of an attack is normally 0.

Against Armor: Piercing weapons do not cause significant harm to the armor itself.

If trying to attack something with a higher AD behind an object, critical hits only count if confirmed against the higher AD, and you get all attack penalties for attacking either target, other than cover or total cover granted by the obstacle itself.

For example, Bobby "Sledgehammer" Stone is trying to kill a guy wearing fullplate hiding behind a quarter meter of brick with a single swing of his massive hammer. Through the use of Sniper, he easily gets a critical hit on both the wall's AD (3) and the guy's (4), for a relatively low amount of damage, considering his 4 Strongman, of only 21. Since he has 2 Demolition, each 2 points of obstacle damage reduces the attack's damage by 1. The smashed granite's 3 HP and 5 Toughness takes away 7 points of damage (the 21 goes down to 14 after 14 points). The poor sod's fullplate reduces damage further to 9, so he only takes 2 Wounds, knocking him unconscious but not killing him. Bobby's reputation is ruined.

The sound created by a breaking object is audible at a distance equal to the original damage roll, squared, in meters, or only half that for Piercing weapons.

A breakdown of the amount of destruction one could expect to cause can be found on the Charts page.

Water: Water is difficult to see through. 100 meters of clear water or 5 meters of murky water grants concealment, and it's impossible to see more than 10 times that far through it.

Timestone: Timestone is a material much like sandstone, aside from its unique interaction with [ time ] effects: If an object would be affected by a [ time ] effect, all timestone in contact with that object is affected as well.

Cherelith: Cherelith is a type of marbled rock, part dark and metallic, part transparent and glowing blue. Any significant quantity of Cherelith emits bright illumination out to 2 meters, and deals 1d8 Light damage to creatures in a 10 meter spray each round.

Airsteel: Airsteel is air that has been linked to form a single solid shape. 1 wound is enough to break the link and shatter the Airsteel, independent of its size. Airsteel, being air, looks like air.

Attacking Projectiles

Unless otherwise specified, projectiles have AD 10, GD 10, 1 HP, and 9 Toughness. The Toughness, AD, and GD get adjusted according to its weight, with Toughness getting the damage modifier as a bonus, while AD and GD get it as a penalty (Thus, a < 1 kilogram projectile like an arrow or bullet would have AD 16, GD 16, and Toughness 3, while a 100 kilogram projectile like a large missile would have AD 10, GD 10, and Toughness 9). Lasers and beams of light are not projectiles, and so cannot be attacked.
