Hazards are dangers that are from the environment or non-sentient creatures.<ref>User description</ref> The {{pub|Dungeon Master's Guide (5e)}} lists the following hazards as examples:

==Dungeon Hazards==
<ref name="dmg5.105">{{Cite Pub|Dungeon Master's Guide (5e)|pages=105}} Licensed: &copy; Wizards of the Coast {{fairuc}} (summarized).</ref> Hazards are described as environmental damages.

===Detecting Hazards===
<ref name="dmg5.105" /> Unless {{srd5lc|Hidden}}, no {{srd5lc|Ability Check}} is needed to detect a hazard. Hazards that are hidden (naturally blend with the environment or appear to be something harmless) can be detected and identified with a {{SRD5|Nature}} {{srd5lc|Check}}. (see {{pub|DMG5e}} for appropriate {{SRD5|DC}} guidelines)

===Hazard Severity===
<ref name="dmg5.105" /> When a {{SRD5|GM}} determines how deadly a hazard should be included in an adventure, compare damage dealt by the hazard or how hard it is to overcome the resulting condition. (see {{pub|DMG5e}} chapter 8)

==List of Hazards==

===Brown Mold===
<ref name="dmg5.105" /> Brown mold is an inanimate {{srd5lc|Ooze}}-like {{srd5lc|Plant}} ({{5edlc|Fungus}}) that absorbs heat from its surroundings. It typically covers a 10-foot diameter patch. A creature within 5 feet of it takes {{srd5lc|Cold}} damage ({{SRD5|Constitution}} {{srd5lc|Save}} to reduce damage). The mold is {{srd5lc|Immune}} to {{srd5lc|Fire}} damage, and even spreads if subjected to it. Ironically, it can be destroyed by magical {{srd5lc|Cold}} damage.

===Green Slime===
<ref name="dmg5.105" /> Green slime is another inanimate ooze-like fungus (plant). It is bright green and moist. It is often found on walls or ceilings. Patches of green slime are usually about 5 feet in diameter. It does not have sight, but can detect creatures below it, and voluntarily fall on them ({{SRD5|Dexterity}} {{srd5lc|Save}} to avoid). 

Contact with the slime causes {{srd5lc|Acid}} damage to flesh and other organic material, as well as to metal. The slime continues to damage creatures and objects until it is scraped off or destroyed. 

Green slime can be destroyed by sunlight; cold, fire, or {{srd5lc|Radiant}} damage; or by magic that cures {{srd5lc|Disease}}.

===Rapture Weed===
<ref name="gos126">{{Cite Pub|Ghosts of Saltmarsh|pages=126}} ({{pub|The Final Enemy (5e)}}) Licensed: &copy; Wizards of the Coast {{fairuc}} (summarized).</ref> Rapture weed is a plant that grows deep underwater, on shelves of trenches. Touching rapture weed causes the {{srd5lc|Poisoned}} condition for a quarter of a day. Those poisoned often experience hallucinations and euphoria. 

If consumed, it has a chance of causing the {{srd5lc|Incapacitated}} condition (experiencing terrifying hallucinations) while poisoned. After recovering from being incapacitated, the ingesting creature must succeed on a {{SRD5|Wisdom}} save or be afflicted with long-term {{srd5lc|Madness}}.

===Webs===
<ref name="dmg5.105" /> Webs are long, sticky treads woven by creatures (such as a {{srd5lc|Giant Spider}}), usually encountered (as a hazard) covering an area of ground or blocking a passage. Creatures that attempts to go through a webbed area must attempt a {{SRD5|Dexterity}} save or become {{srd5lc|Restrained}}. A restrained creature may attempt to free itself by succeeding on an {{SRD5|Athletics}} or {{SRD5|Acrobatics}} check.

A 10-foot {{srd5lc|Cube}} of webs have the following characteristics: {{SRD5|AC}} 10; 15 {{SRD5|HP}}; {{srd5lc|Vulnerability}} to {{srd5lc|Fire}} damage; {{srd5lc|Immunity}} to {{srd5lc|bludgeoning}}, {{srd5lc|Piercing}}, and {{srd5lc|Psychic}} damage.

===Yellow Mold===
<ref name="dmg5.105" /> Yellow mold is another inanimate ooze-like fungus (plant). Typical patches have a 5-foot diameter. When touched it projects a {{srd5lc|Cloud}} of spores in a 10-foot cube. Creatures that contact the cloud of spores take {{srd5lc|Poison}} damage and become poisoned ({{SRD5|Constitution}} save to avoid). If poisoned, a creature continues to take poison damage until it succeeds. Sunlight or fire damage will destroy a patch of yellow mold.

==Weather==
<ref name="dmg5.109110">{{pub|DMG5}} p.109-110</ref> Weather can also be a hazard.

===Extreme Cold===
<ref name="dmg5.109110" /> Cold below 0 degrees Fahrenheit for a period of time requires a Constitution save to avoid gaining a level of {{srd5lc|Exhaustion}}. Wearing cold weather gear can negate the need for a save, and creatures with immunity to cold or adapted to cold climates automatically save.

===Extreme Heat===
<ref name="dmg5.109110" /> Heat above 100 degrees Fahrenheit for a period of time, without water to drink, requires a Constitution save to avoid gaining a level of exhaustion. The save get harder to succeed with continued exposure, {{srd5lc|Armor}} ({{SRD5|Medium Armor|medium}} or {{srd5lc|Heavy Armor|heavy}}), or heavy clothing. Creatures immune to fire damage or adapted to hot climes automatically succeed the saves.

===Strong Wind===
<ref name="dmg5.109110" /> Strong with can cause a number of effects:
* Higher difficulty on {{SRD5|Ranged Weapon Attack}}s
* More difficult {{SRD5|Perception}} checks that rely on hearing.
* May extinguish small fires and disperse fog or other {{srd5lc|Cloud}}s
* Make it difficult to {{srd5lc|Fly}}
* If it picks up sand, dust, or debris cause difficulty on Perception checks that rely on sight.

===Heavy Precipitation===
<ref name="dmg5.109110" /> Heavy rain or snow creates areas that are {{srd5lc|Lightly Obscured}}. Heavy rain also extinguishes small fires and can cause Perception checks that rely on hearing to be more difficult.

==High Altitude==
<ref name="dmg5.110">{{pub|DMG5}} p.110</ref> Above 10,000 feet, travel is more taxing (2:1 for determining how long one can travel).

Creatures can become acclimated to this after a month at this elevation, but not to heights of 20,000 or more. Although creatures native to such climes are acclimated.

==Wilderness Hazards==
<ref name="dmg5.110111">{{pub|DMG5e}} p.110-111</ref> Wilderness hazzards also present dangers. Some are easy to spot (ex. slippery ice or razorvine), not requiring a check to spot. Others may require a {{SRD5|Nature}} check to spot (see {{pub|DMG5e}} chapter 8 for determining DCs).

===Desecrated Ground===
<ref name="dmg5.110111" /> Some areas are infused with evil or malevolence. In addition to the Nature check mentioned above, {{5espell|Detect Evil and Good}} will certainly detect it. {{SRD5|Undead}} on desecrated ground have {{srd5lc|Advantage}} on {{srd5lc|Saving Throw}}s. {{SRD5|Holy Water}} can remove the desecration from a 10-radius area. The {{5espell|Hallow}} spell can also remove desecration.

===Frigid Water===
<ref name="dmg5.110111" /> A creature can be immersed in frigid water for a time without harm dependent on its Constitution. After that time, it gains exhaustion (Constitution save to avoid). Creatures with {{srd5lc|Resistance}} to cold damage and creatures adapted to it automatically suscceed. 

===Quicksand===
<ref name="dmg5.110111" /> Quicksand is a mixture of sand and water that pulls heavy creatures and objects to its bottom. Typical patches of quicksand enclose a 10-foot-{{srd5lc|Cube|cubic}} volume. Creatures (or heavy objects) that enter quicksand immediately sink 2-5 feet into the quicksand. If not completely submerged, can make a {{SRD5|Strength}} check to escape, as can another creature to pull a partially- or fully-submerged creature out. Otherwise a creature will continue to sink each turn. A creature completely submerged cannot breathe (see {{SRD5|Suffocation}}).

===Razorvine===
<ref name="dmg5.110111" /> Razorvine is an inanimate plant that clings and climbs surfaces (much like ivy). A creature in contact with razorvine must succeed on a Dexterity save or take {{srd5lc|Slashing}} damage from its blade-like thorns.

===Slippery Ice===
<ref name="dmg5.110111" /> Slippery ice is {{srd5lc|Difficult Terrain}}. Creatures on slippery ice must succeed on an Acrobatics check or fall {{srd5lc|Prone}}.

===Thin Ice===
<ref name="dmg5.110111" /> Thin ice has a weight limit. If a creatures weight (including what they carry) exceeds this they fall through.
