Taking the Heat

2014-07-30_23.45.16.jpg

The Athasian sun is a punishing ball of fire that beats its fury down on the parched land below. As the sun rises the heat intensifies until it can set fire to paper and cook flesh.

4am – 6am 5 to 14°C (Moderate)
6am – 8am 15 to 29°C (Warm)
8am – 10am 30 to 39°C (Hot)
10am – 12am 40 to 59°C (Severe Heat)
12am – 2pm 60°C+ (Extreme Heat)
2pm – 6pm 40 to 59°C (Severe Heat)
6pm – 8pm 30 to 39°C (Hot)
8pm – 10pm 15 to 29°C (Warm)
10pm – 12pm 5 to 14°C (Moderate)

Hot
In this temperature band, unprotected characters must make successful Fortitude saving throws each hour (DC 15, +1 for each previous check) or take 1d4 points of non-lethal damage. Characters wearing heavy clothing or any kind of armour take a -4 penalty on their saves. Characters whose protection against heat is at least level 1 (such as the Heat Endurance feat, or wearing desert clothing) are safe at this temperature and need make no checks.

Severe Heat
In this temperature band, unprotected characters must make successful Fortitude saving throws once every 10 minutes (DC 15, +1 for each previous check) or take 1d4 points of non-lethal damage. Characters wearing heavy clothing or any kind of armour take a -4 penalty on their saves. To be completely protected against severe heat, a character must have at least protection level 2 or higher (such as having the Heat Endurance Feat and wearing desert clothing). A character with protection level 1 is considered partially protected and such characters must attempt this saving throw only once per hour.

Extreme Heat
In this temperature band, unprotected characters take 1d6 points of lethal damage per 10 minutes (no save). In addition, unprotected characters must make successful Fortitude saves (DC 15, +1 for each previous check) every 10 minutes or take 1d4 points of non-lethal damage. Characters wearing heavy clothing or any kind of armour take -4 penalties on their saves. In addition, those wearing metal armour or coming into contact with very hot metal are affected as if by a heat metal spell (which lasts as long as the character remains in the area of extreme heat). A character must have protection level 3 or higher to be protected against extreme heat. Level 2 is considered partial protection, and such characters take damage and make saving throws once per hour instead of once per 10 minutes. Level 1 provides no protection.

Heat Stroke
A character who takes any non-lethal damage from heat is fatigued. The non-lethal damage and the accompanying fatigue cannot be healed until the character gets cooled off – by reaching shade, being targeted by endure elements etc. Once the character reaches a temperature of warm or lower the character responds normally to healing that removes non-lethal damage. Once all the damage is healed the fatigue is also removed.

Dehydration
As the body loses fluids, biological processes begin to break down. This leads to a drop in pallor, shaking, nausea and eventually a complete collapse of the nervous system. Though dehydration can occur in any environment, the combination of high heat and low humidity in waste environments makes it an omnipresent threat there.

In the heat of Athas a character must consume 4 litres of water a day to avoid dehydration. In particularly hot environments above 30°C characters need double the amount. The amount of water required to avoid dehydration increases by a further 4 litres per temperature band higher than hot. A creature can go without water for a number of hours equal to 24 + its Constitution Score. After this point, the creature must make a successful Fortitude Save (DC 10, +1 for each previous check) or take 1d6 points of non-lethal damage. In particular hot environments (those above 30°C) the time a creature can go without water is reduced.

Hot 12 + Con hours
Severe Heat 6 + Con hours
Extreme Heat 3 + Con hours

Characters who have taken non-lethal damage from lack of water are considered dehydrated and become fatigued. In addition, if a dehydrated character would take nonlethal damage from hot conditions, that damage instead becomes lethal damage. A character who has taken non-lethal damage from lack of water must be treated with long-term care (see the Heal skill) to recover. This treatment requires 24 hours of care and double the normal amount of water required per day for the conditions. If the character has also taken damage from hot conditions, increase the DC of the check by 5 and double the time to recover to 48 hours. Once the Heal check has succeeded, the damage can be restored through the normal means.

Sunburn
Sunburn is a serious hazard when travelling in the waste. A mild sunburn is merely distracting, but more severe burns can be life-threatening. Avoiding sunburn requires covering up exposed skin, wearing hats or robes, or carrying a parasol. Beings native to torrid climates have developed dark skin pigmentation to protect against the sun. Of course, wearing heavy clothing carries its own risks (increasing the likelihood of succumbing to heat stroke), and sunlight reflected from light-coloured surfaces can still reach beneath a hat or shade.

Characters who take even minimal care to protect their skin from sunlight are not subject to sunburn. Wearing a desert outfit is also sufficient. If a character is out in the sun unprotected, after six hours the character is mildly sunburned and takes 1 point of non-lethal damage. After a further six hours exposure the character develops severe sunburn and immediately takes 2d6 points of non0lethal damage and a -2 penalty on Fortitude saves to avoid damage or fatigue from heat dangers until the non-lethal damage is healed.
