Outside the safety of city walls, the wilderness is a dangerous place, and many adventurers have gotten lost in its trackless wilds or fallen victim to deadly weather. The following rules give you guidelines on running adventures in a wilderness setting. | Outside the safety of city walls, the wilderness is a dangerous place, and many adventurers have gotten lost in its trackless wilds or fallen victim to deadly weather.

Wading through tainted water can also communicate filth fever, as tiny drops of the water get on the character's hands, clothes, and face and can later be transferred to the mouth, nose, or eyes as the character moves about. It is more difficult to contract a disease in this way, though. When wading or swimming through tainted water, a character receives a +2 circumstance bonus on her save to resist contracting filth fever. | Wading through tainted water can also communicate filth fever, as tiny drops of the water get on the character's hands, clothes, and face and can later be transferred to the mouth, nose, or eyes as the character moves about.

===Altitude=== | ===Altitude=== | ||
| Line 108: | Line 104: | ||
High Peak (more than 15,000 feet): The highest mountains exceed 15,000 feet in height. At these elevations, creatures are subject to both high altitude fatigue (as described above) and altitude sickness, whether or not they're acclimated to high altitudes. Altitude sickness represents long-term oxygen deprivation, and affects mental and physical ability scores. After each 6-hour period a character spends at an altitude of over 15,000 feet, he must succeed on a Fortitude save (DC 15, +1 per previous check) or take 1 point of damage to all ability scores. Creatures acclimated to high altitude receive a +4 competence bonus on their saving throws to resist high altitude effects and altitude sickness, but eventually even seasoned mountaineers must abandon these dangerous elevations. | High Peak (more than 15,000 feet): The highest mountains exceed 15,000 feet in height.

Native flora, especially tall trees, have generally adapted to seasonal storms and rarely come down due to rainfall. At times, though, a particularly strong storm can erode the soil and pound a tree with enough force to cause it to topple, possibly setting off a chain reaction. Anyone in the path of a falling tree must make a DC 14 Reflex save to leap clear or take 3d6 points of damage. Fallen trees can block routes, but travelers can usually climb over the trees, which measure anywhere from 5 to 20 feet in diameter. Fallen trees can, however, block river travel and require travelers to abandon their boats or to drag them out of the river and portage them around the obstruction. | Native flora, especially tall trees, have generally adapted to seasonal storms and rarely come down due to rainfall.

===Forest Fire=== | ===Forest Fire=== | ||
| Line 232: | Line 222: | ||
Forest fires naturally produce a great deal of smoke. A character who breathes heavy smoke must make a Fortitude save each round (DC 15, +1 per previous check) or spend that round choking and coughing. A character who chokes for 2 consecutive rounds takes 1d6 points of nonlethal damage. Smoke also provides concealment to characters within it. | Forest fires naturally produce a great deal of smoke.

===Lightning=== | ===Lightning=== | ||
| Line 284: | Line 272: | ||
Lightning strikes also occur during storms. It is exceedingly rare for a creature to be struck by lightning, though such an unlucky character would suffer between 4d8 and 10d8 points of electricity damage from the strike. Lightning strikes rarely produce forest fires, yet on the plains (see Plains Terrain) it's possible for a strike to ignite a drought-plagued field and start a wildfire. | Lightning strikes also occur during storms.

===Quicksand=== | ===Quicksand=== | ||
| Line 310: | Line 297: | ||
Creatures with tremorsense can easily locate patches of quicksand due to the difference in vibrations and density of the pits of sand. Creatures with a burrow speed treat quicksand as difficult terrain, but they can still suffer the effects of suffocation if they are submerged in it and do not free themselves. Creatures that can breathe water also suffocate in quicksand, but they take twice as long to do so. Water Dangers The serpentine rivers and still ponds of the jungle both sustain life and take it. All creatures, be they animals, monsters, or humanoids, require water in one form or another, and the local watering hole is the common bond that both predator and prey share, albeit not peacefully. Slow-moving jungle rivers also make for easy ship and barge travel, and where their overgrown banks turn sandy the rivers can provide a welcome respite from underbrush for those traveling on foot. The biggest danger inherent in any jungle water supply is from the creatures that live within it or set ambushes near its banks, waiting for weaker creatures to approach and drink. Yet along with high-profile dangers like crocodiles, hippopotamuses, and carnivorous fish, the lakes and rivers also hold many lesser dangers, some inherent to the water itself. | Creatures with tremorsense can easily locate patches of quicksand due to the difference in vibrations and density of the pits of sand.

| Line 318: | Line 304: | ||
Slow Suffocation: A Medium character can breathe easily for 6 hours in a sealed chamber measuring 10 feet on a side. After that time, the character takes 1d6 points of nonlethal damage every 15 minutes. Each additional Medium character or significant fire source (a torch, for example) proportionally reduces the time the air will last. Once rendered unconscious through the accumulation of nonlethal damage, the character begins to take lethal damage at the same rate. Small characters consume half as much air as Medium characters. | Slow Suffocation: A Medium character can breathe easily for 6 hours in a sealed chamber measuring 10 feet on a side.

A creature can avoid being pulled out to sea with a DC 25 Swim check; otherwise it is pulled 6d6 x 10 feet away from shore. Waters after a tsunami are always treated as rough or stormy, barring magical conf lict. A creature caught in a collapsing building takes 6d6 points of damage (DC 15 Reflex save for half), or half that amount if the building is particularly small. There is a 50% chance that the creature is buried (as for a cave-in), or the tsunami may tear the building apart, freeing the creature from the rubble. | A creature can avoid being pulled out to sea with a DC 25 Swim check; otherwise it is pulled 6d6 x 10 feet away from shore.

===Volcano=== | ===Volcano=== | ||
| Line 366: | Line 350: | ||
Some volcanic eruptions create a devastating wave of burning ash, hot gases, and volcanic debris called a pyroclastic flow that can travel for miles. Treat a pyroclastic flow as an avalanche traveling at 500 feet per round, combined with the effects of poisonous gas listed above. Contact with the searing-hot debris of the flow causes 2d6 points of fire damage per round, while any creature buried in the flow suffers 10d6 points of damage per round. Only reality-warping magic like miracle or wish can turn aside or impede a pyroclastic flow. | Some volcanic eruptions create a devastating wave of burning ash, hot gases, and volcanic debris called a pyroclastic flow that can travel for miles.
