Building Hazards

Building hazards designed for your game allows you to customize them to match your story, location, and needs, as well as to surprise the other players at every turn. There’s no wrong way to create a hazard, but this guide presents the information in the order you might see it in a hazard stat block.

Concept

The first thing you’ll need is a concept for your hazard.

What level is your hazard? Will it be simple or complex? Is it a trap, a haunt, an environmental hazard, or something else? If it’s a trap, is it mechanical, magical, or both? This is a good time to brainstorm the hazard’s name and description, as this will help you decide how the hazard can be disabled.

The following information builds on concepts from Building Creatures.

Hazard Types

The three main types of hazards are traps, environmental hazards, and haunts.

Traps are usually built or placed, though they can also form accidentally, such as if a magic portal, through millennia of disuse, malfunctions as its magic warps. Mechanical traps always have some physical component, whereas purely magical traps typically don’t. Magical traps can usually be counteracted by dispel magic, and those without a listed proficiency rank for Stealth can be found using detect magic. Thievery is the most common skill used to disable traps.

Environmental hazards are either living things, like dangerous spores and molds, or simply features of the terrain or environment, like avalanches or rockslides. While they are always physical, some environmental hazards can’t reasonably be attacked or damaged, such as a cloud of poisonous gas or a patch of quicksand. Survival is the most common skill used to disable environmental hazards.

Haunts are spiritual hazards, usually formed when the spiritual essence of a location is imprinted with the instincts and emotions from a living being’s demise. Because haunts lack matter, they rarely involve a physical component, and when they do, that component is generally incorporeal or might even be damaged only by positive energy. The skills and options used to disable haunts vary, though using Religion for an exorcism is common. However, even with a successful check to disable a haunt, it can reoccur until its unfinished business is resolved. Typically, successfully disabling or enduring a haunt provides clues to determine what it would take to lay it to rest permanently.

Understanding and Choosing Statistics

Much like for creatures, hazard statistics can be extreme, high, or low (hazards don’t need as much granularity, so they usually don’t have moderate or terrible values for their statistics). While they are defined in creature creation, when building a hazard, you’ll use the values slightly differently.

Extreme: While extreme values remain world-class statistics that are extremely difficult to meet or exceed, unlike with monsters, almost all hazards have one extreme statistic because hazards normally activate only if they have gone unnoticed or if someone critically failed to disable them. Does it have an extreme Stealth DC that makes it incredibly hard to find, an extreme Disable DC that makes it perilous to disable, or an extreme save DC that makes it deadly in the event it triggers? These are the most common choices, as each affects a different phase of encountering the hazard.

High: This is a capable level, and can generally serve as a baseline value; this value for hazards covers what would be the high and moderate ranges for creatures.

Low: If a hazard has a weakness, like a poor Reflex save for a bulky mechanical trap or an easy DC to disable for a hard-to-find trap, it usually has a low value. If you need something even lower, use a terrible value from Building Creatures, or just an incredibly low value like the Armageddon orb’s Stealth.

Stealth and Disable

When determining a hazard’s combat statistics, first decide how the hazard can be located and how hard it is to disable.

A hazard where the main challenge is how difficult it is to find, like a hidden pit, might have a very different effect for its level than a hazard out in plain sight, daring a PC to try to disable it, like the Armageddon orb.

Table 2–13: Stealth and Disable DCs

22 55 52 45 to 41
23 56 53 46 to 42
24 58 55 48 to 43

When deciding how your hazard is disabled, come up with a narrative description of how it would happen, which will inform which methods and skills disable the hazard. You’ll need to decide the proficiency rank necessary to find the hazard as well as disable it with each method.

Remember, a hazard without a listed rank next to its Stealth DC is obvious enough that creatures can find it without Searching, and magical hazards without a listed rank are not normally protected against detect magic. Most hazards built by intelligent creatures are concealed have at least a trained rank. Table 2–14 indicates the high and moderate proficiency requirements by level; you can use lower proficiency ranks than the ones listed, and if you use the high rank, consider a secondary, perhaps less-efficient method to disable the hazard using a lower rank. For instance, the bloodthirsty urge haunt in the core rules can be disabled with master Religion, or by a higher DC with expert Diplomacy.

If you need a Stealth modifier for a complex hazard, just subtract 10 from the listed DC.

Table 2–14: Minimum Proficiency
Levels High Moderate
0 or lower Untrained Untrained
1–4 Trained (expert for Perception) Trained
5–8 Expert Trained
9–18 Master Expert
19 or higher Legendary Master

Defenses

If there’s a physical component that a character could break, you’ll need to determine the hazard’s AC, Fortitude save, and Reflex save, using the extreme, high, and low values (preceded by E, H, or L on the table) as well as its Hardness, HP, and Broken Threshold (BT). When building a purely magical or formless hazard, you can skip this section.

24 54 51 48 +46 +42 +36 46–50 180–188

* The Broken Threshold is usually half the hazard’s HP.

Some hazards, even high-level ones, don’t make sense with a high Hardness value. In those cases, you can skip the Hardness and use the HP values from table 2–7: Hit Points. Especially for complex hazards, you might want to divide the durability over multiple sections, located in different positions, to encourage teamwork and mobility.

Offense

Almost all hazards need an attack bonus or a save DC, and hazards that deal damage need to list a damage value. Simple hazards deal about twice as much damage as complex hazards and have an attack bonus even higher than the extreme attack bonus for a creature (abbreviated as S. Atk in Table 2–16: Offense). Complex hazards usually have attack bonuses akin to a high attack bonus for a creature (abbreviated as C. Atk in Table 2–16).

You can adjust them further using Table 2–9: Attack Bonus if your hazard needs it. Simple hazard DCs aren’t as high for their level as their attack bonuses are, since effects with DCs usually have some effect even on a successful saving throw; use the EDC and HDC columns for extreme and hard DCs on Table 2–16: Offense below.

The damage columns on the table give a damage expression you can use, followed by the average damage in parentheses. If you want to make your own damage expression, remember that average damage is 2.5 for a d4, 3.5 for a d6, 4.5 for a d8, 5.5 for a d10, and 6.5 for a d12.

Example Simple Hazards

When designing a simple hazard, make sure to select an appropriate trigger and effect. Often, a simple hazard that merely damages its target is little more than a speed bump that slows down the game without much added value, so think about the purpose of your hazard carefully, both in the story and in the game world, especially when it’s a hazard that a creature intentionally built or placed in that location. A great simple hazard does something interesting, has a longer-lasting consequence, or integrates with the nearby inhabitants or even the encounters in some way (you can find more information on integrating hazards with encounters in Dynamic Encounters).

A simple hazard uses its reaction when triggered.

Air Bubbles (3pp)

Source NW:NEH


Occasionally, sea dwelling civilizations create pockets of breathable air for surface dwellers visiting their domain, and these large permanent air bubbles occasionally fill underwater caves or “breather” districts of cities. These magically-created air bubbles displace water but contain breathable air for surface dwellers, which is never exhausted.

More commonly, small magical geysers give rise to temporary bubbles of breathable air which balloon out from rocky lakebeds, ocean floors, and similar underwater features.

These bubbles take up a 5-foot square and provide enough air for a Large or smaller air-breathing creature to refill its lungs, allowing it to reset the clock on holding its breath.

Because air bubbles displace water, swimming into one makes continuing to swim somewhat difficult, imposing a –10 penalty on Athletics checks to Swim in the round in which a creature encounters an air bubble, and on the following round. These magical geysers typically produce air bubbles at a rate of about 1 bubble every 30 seconds, though some have been known to be produced more frequently or infrequently.

When created for the convenience of surface dwellers, these air bubbles are spaced frequently enough to allow comfortable sea travel.

Brown Mold Hazard 2

Source GMG

Environmental Fungus

Stealth DC 21 (trained)


This unassuming fungus leeches heat out of the air.

Disable DC 18 Survival (trained) to safely remove the mold

Emit Cold (aura, cold); 5 feet. Brown mold deals 2d6 cold damage to nearby creatures.

AC 18; Fort +11, Ref +5

HP 30 (BT 15); Immunities critical hits, fire, object immunities, precision damage; Weaknesses cold 10


Leech Warmth [reaction] Trigger Fire comes within 5 feet of the brown mold; Effect The brown mold expands into every square adjacent to its space. As it grows, it pulls more heat from its surroundings, dealing 2d6+6 cold damage (DC 18 basic Fortitude save) to creatures within 10 feet after it expands.


Reset After expanding, the brown mold can’t grow again for 1 day.

Dragonstorm Hazard 18

Source PAP150

Rare Environmental Magical

A massive storm stirs in the skies. As specific events begin during the three waves of the manifestation’s retribution, the dragonstorm wreaks localized havoc.

Stealth +40 (legendary)


Disable The dragonstorm can’t be disabled—only endured. See source material for information on ending this hazard’s effects.


Localized Dragonstorm [reaction] (air) Trigger A new wave begins; Effect Roll 1d10 to determine which effect manifests from the following possibilities. The placement of these effects is guided by Dahak’s will, and they should manifest in the most detrimental locations possible to the PCs.

d10 Result
1–2 Acid Rain (acid) A torrent of acid drenches creatures in a 20-foot burst. Creatures in the area take 6d10 acid damage (DC 42 basic Reflex save). Creatures that critically fail also take 5 persistent acid damage.
3–4 Freezing Wind (cold) A barrage of freezing wind and hail assaults all creatures in a 20-foot burst. Creatures in the area take 3d10 cold damage and 3d10 bludgeoning damage (DC 42 basic Reflex save). Creatures that critically fail are slowed 1 for 1 round.
5–6 Bolts of Lightning (electricity) Several bolts of lightning strike all creatures in a 20-foot burst. Creatures in the area take 6d10 electricity damage (DC 42 basic Reflex save). Creatures that critically fail their saves become blinded and deafened for 1 round.
7–8 Flaming Vortex (fire) Gouts of flame fall on all creatures in a 20-foot burst. Creatures in the area take 6d10 fire damage (DC 42 basic Reflex save). Creatures that critically fail their saves also take 5 persistent fire damage.
9–10 Poison Miasma (poison) Poisonous mist rolls forth, covering a 20-foot burst for 1 round. Creatures within the mist become concealed, and creatures outside it become concealed to creatures within it. Creatures within the mist take 6d10 poison damage (DC 42 basic Fortitude save). Creatures that critically fail their saves become enfeebled 2.

Flying Water (3pp)


A magical phenomenon sometimes resulting from the interference of wizards, and other times occurring as a result of ambient magic in the world, flying water is just as it sounds. A large torrent of water forms a long stream resembling a worm or snake, connecting one body of water with another, or, in the case of some large bodies of water, connecting one part of itself with another. Typically, flying water forms a 30-foot-diameter tube of water which can be swum in or sailed upon, with some difficulty. The DC of Athletics checks made to Swim in flying water are increased by 5. Additionally, a creature who sinks far enough can fall out of the bottom of a band of flying water, taking fall damage as appropriate for the distance of the fall. Flying water always has a current heading in one direction, but any creature in flying water is also subjected to the effects of any wind in the area. A flying creature must succeed on an Athletics check to Swim through the flying water if it encounters it or become entangled in its current. The DC of any skill checks made to sail a vessel on top of a band of flying water are increased by 10.

Ghostly Choir Hazard 6

Source GMG

Haunt

Stealth DC 20 (expert)


A choir of lost souls rises out of the floor, singing an eerie chant that terrifies its listeners and buffets their bodies with walls of sound.

Disable DC 28 Performance (trained) to disrupt the song’s resonance with another tune or DC 28 Religion (trained) to ritually silence the spirits


Profane Chant [reaction] (auditory, emotion, enchantment, fear, mental, occult) Trigger A creature moves within 10 feet of the section of floor from which the choir can arise; Effect The choir rises, and its song deals 4d8+18 mental damage to non-evil creatures within 30 feet of the souls’ spectral forms. Affected creatures must each attempt a DC 24 Will save.

Critical Success The creature is unaffected.

Success The creature takes half damage and becomes frightened 1.

Failure The creature takes full damage and becomes frightened 2.

Critical Failure The creature takes double damage. It also becomes frightened 3 and fleeing for 1 round.

Golden Ice (3pp)

Source NW:NEH


In areas where the cold is particularly extreme, raw magical energy occasionally becomes frozen as a shimmering plane of ice. While the color of these odd ice formations varies, gold is the most prevalent, and thus “golden ice” was coined as the name for this phenomenon. Ice like this has a habit of forming in inconvenient places, such as in front of doors, at the mouths of caves, or over sources of fresh water; this is partially due to the fact that such ice normally forms as the result of long-standing protective spells, enchantments, or wards, and partially due to magic’s natural tendency to meddle with mortals. Whatever the case, golden ice is as hard as mithral of the same thickness and suffers only half damage from non-magical sources, regardless of composition.

Magical fire, however ignores the hardness of golden ice and deals 5 times its normal damage to golden ice, usually melting the formation. A spellcaster can spend 1d12 hours in an area where the natural temperature is –5 degrees or colder and expend a spell of 5th level or higher to create a 1 foot thick, 5-foot by 5-foot sheet of golden ice within 30 foot.

The spellcaster may expend additional spells slots to increase the dimensions of this sheet by an additional number of feet equal to the total combined level of the expanded spell slots, though the sheet remains 1 foot thick. Attempting to create a complex work of art in this way requires an appropriate skill check. Golden ice automatically melts if it spends more than 24 hours in an area warmer than –5 degrees.

Grasp of the Damned Hazard 17

Source GMG

Haunt

Stealth DC 43 (master)


These desperate spirits are the echoes of people who committed great atrocities in the name of an evil god.

Now, they are left with only the knowledge that their souls have been damned, and the unwavering belief that they can better their fate by providing powerful sacrifices for their fiendish masters.

Disable DC 46 Religion (master) to inspire a deity to intervene and counteract the ritual


Mark for Damnation [reaction] (death, divine, necromancy) Trigger Three or more sentient living creatures of 13th level or higher enter the haunt’s area; Effect The haunt deals 6d12+35 negative damage to each creature in the haunt’s area, and each creature must attempt a DC 40 Will save.

Critical Success The creature takes no damage and is doomed 1.

Success The creature takes half damage and is doomed 1.

Failure The creature takes full damage, becomes doomed 2, and is marked for damnation.

Critical Failure The creature takes double damage, becomes doomed 3, and is marked for damnation.

If a creature that is marked for damnation dies within the next 24 hours, including from the haunt’s damage, its soul is immediately dragged away to the plane of the evil deity that the damned spirits served, where the creature’s soul is held captive by one of that deity’s powerful servitors.

Only wish and similarly potent effects are able to recover the lost soul directly; however, it is also possible to recover the soul by journeying to the evil plane and defeating the soul’s captor.

HP 200 (BT 100); Immunities critical hits, object immunities, precision damage; Weaknesses cold 20, fire 20


Dissolving Ambush [reaction] Trigger A creature walks beneath the slime; Effect The green slime drops on top of the creature, attempting to dissolve it into a nutritious slurry. The target must attempt a DC 28 Reflex save.

Critical Success The target leaps out of the way, and it is unaffected.

Success A small amount of the slime splashes onto the target. The target is drained 1.

Failure The slime lands on its target. The target is drained 1, and this condition value increases by 1 at the end of its turn each round until the slime is removed. If the target reaches drained 4, the next time its drained value would increase, it dies and collapses into a slurry of nutrients. A slime covering a target can no longer be removed through Survival checks, and damage dealt to the slime is also dealt to the target (applying the target’s immunities, weaknesses, and resistances rather than those of the green slime).

Critical Failure The slime completely coats its target. This has the same effect as a failure, except the target is immediately drained 2, becomes drained 4 after 1 round, and dies after 2 rounds.

Iron Needles

Source NW:NEH


Iron needles (sometimes called razor leaves) are extraordinarily sharp foliage affected by magic, usually at the hand of the fey in an attempt to preserve the beauty of the forest from animals and humanoids. Trees, bushes, and even smaller undergrowth might have foliage of this kind, and it can often be difficult to discern with the naked eye.

Typically a Perception (expert) check is required to notice the augmentation on the foliage, though occasionally such magically altered leaves have an iron hue or gleam in the sun, making them readily noticeable. Creatures who come into contact with these leaves and needles become cut, suffering minor piercing and slashing damage. A creature climbing a plant augmented in this way suffers a penalty on their Athletics check to Climb equal to the amount of damage dealt by the iron needles. Iron needles affecting undergrowth deal minor piercing and slashing damage to creatures moving through the area, unless they take special care to avoid the undergrowth; if they do, they treat the undergrowth as greater difficult terrain (instead of normal difficult terrain).

A creature in heavy armor takes only half damage from iron needles. If used as an improvised weapon, a branch covered in iron needles deals an additional 1d4 points of piercing and slashing damage.

Jealous Abjurer Hazard 11

Mystical Mirages (3pp)

Source NW:NEH


Hot desert sand, dehydration, and shimmering sunshine occasionally combine to produce mirages in the minds of intelligent creatures. When powerful magicians experience mirages, their natural magical abilities can give these illusions some semblance of reality. A mystical mirage takes on one of the following forms and can be interacted with once before disappearing. While mystical mirages are illusory, the traces of magic they possess can produce very real and useful (or dangerous) effects. The types of mystical mirages are as follows.

Oasis (3pp)

A shimmering pool of sky-blue water surrounded by gentle palm trees can be seen in the distance. This illusion provides the sensation of cool air in a 30-foot area. If you drink from the water provided by the illusion, your thirst is alleviated as if you had consumed enough water to sustain you for 1 day. The mystical mirage is visible to you until you drink from the water, at which point it vanishes from your mind (though not necessarily from the minds of your companions).

Peddler (3pp)

Source NW:NEH


A humanoid dressed in a brown cloak approaches from the distance, sometimes accompanied by a horse or dromedary. While the exact appearance of this peddler varies, its right hand is always an unmistakable crimson shade. The peddler offers intelligent creatures the chance to purchase rare and mystical items with a value of up to 100,000 gp at a 10% discount. The peddler remains for up to 1 hour before vanishing. Items purchased from the peddler last until a creature leaves the desert, at which time there is a 50% chance magical items purchased from the peddler turn to sand, leaving behind only a ruby the same shade as the peddler’s right hand, worth 50% of the item’s purchase price (including the peddler’s discount).

Pink Snow (3pp)

Source NW:NEH


The creation of good-aligned winter-loving fey, pink snow is an idealized version of regular snow and occupies pristine places not commonly visited by mortals. Pink snow is good to eat, with a sweet sugary taste, and provides the same sustenance as an equivalent weight of berries. Pink snow always makes perfectly round snowballs, and the DC of any Craft check to make structures, sculptures, or other items out of pink snow is reduced by 20, allowing even unskilled children to create wild snow palaces and exotic snowmen.

Evil-aligned creatures hit by a snowball made out of pink snow suffer 1 good damage. This damage is increased to 1d6 if the snowball was thrown by a child or a fey.

Plummeting Doom Hazard 15

Haunt

Stealth DC 40 (master) to hear the echoes of a faraway object crashing into the ground

Four vengeful spirits grab interlopers and toss them off the edge of a nearby 120-foot-tall cliff.


Disable DC 40 Athletics (trained) to push back so forcefully that the spirits fear being thrown off the cliff, or DC 40 Religion (expert) to temporarily seal the spirits away


Call of the Ground [reaction] (divine, abjuration) Trigger A creature approaches within 15 feet of the edge of the cliff; Effect Each spirit attempts to throw a creature within 60 feet of the cliff’s edge off the cliff by attempting a check with a +26 modifier against the target’s Fortitude DC. If the haunt succeeds, the target is thrown over the edge of the cliff, where it then falls 120 feet to the ground.

Until the haunt is defeated, each creature within 60 feet of the cliff’s edge must attempt a DC 40 Will save each time they would spend an action or reaction to Arrest a Fall, Fly, Grab an Edge, or otherwise avoid falling; if they fail the save, the action is disrupted. The haunt automatically attempts to counteract spells that would slow a fall or mitigate the effects of falling, such as feather fall, with a counteract modifier of +32.

Poison Ivy Hazard 3

Source NW:NEH

Environmental Poison

Stealth DC 20


A 20-foot square filled with leafy plants contains an irritating secretion which causes itching and discomfort. Occasionally, magical poison ivy replicates the effects of a different contact poison, in which case the level of this hazard is increased by an amount equal to 1/2 the level of the contact poison and it gains a bonus to the Stealth DC equal to the level of the contact poison.

Disable Survival DC 20 to neutralize the toxin, or Thievery DC 20 to clip the venomous leaves before any harm is done.

AC 10; Fort +4, Ref +2

Harness 0, HP 30; Weaknesses fire 5, slashing 5


Poisonous Touch [Free Action] Trigger A creature touches the poison ivy, either by moving through it or by attacking it with a natural attack or a melee weapon without reach. Effect The target’s skin is irritated for 2d6 days. A successful Fortitude (DC 20) halves this time, while a critical success negates the effect entirely.

A creature whose skin is irritated in this way suffers a –4 penalty on Strength- and Dexterity-based skill checks and starts every combat with the clumsy 3 condition, as it struggles to control its painful rash. Occasionally, magical poison ivy has the additional effects of a contact poison, and any creatures subjected to poisonous touch are also exposed to that poison, which has its usual effect.


Reset Poison ivy which has been clipped or neutralized regrows in 1d8 months. Poison ivy which is destroyed with damage does not regrow and never resets. Triggering poison ivy does not disable the hazard and it does not need to be reset after being triggered.

Spectral Impale [reaction] Trigger A living creature approaches within 15 feet of the mirror, and the mirror is lit with dim or brighter light; Effect Shadowy barbs impale the body of the reflected creature as the haunt makes a shadow barbs Strike.

Melee [one-action] shadow barbs +19, Damage 4d8+9 negative plus sap vitality

Sap Vitality A creature hit by the reflection’s shadow barbs must attempt a DC 22 Fortitude save as the haunt tries to draw a portion of its vital essence into the mirror. The target is drained 1 on a failed saving throw, or drained 2 on a critical failure.


Reset The haunt re-forms after 1 minute, manifesting in any mirror within its infused area (see Special below).

Special Spectral reflections often infuse entire buildings, manifesting in any sufficiently large mirror. The example Hit Points and Hardness given represent a typical mirror reinforced by the haunt; at your discretion, the haunt might appear in reflective surfaces that are harder to destroy. Defeating a manifestation through damage destroys the surface, preventing the haunt from using it again. If this haunt appears in an area with many mirrors, consider giving PCs double or even triple the XP for a typical simple hazard.

Stampede (3pp)

Source NW:NEH


A stampede of wild beasts appears as if from the horizon, charging directly in the path of any intelligent creatures. The stampede is so large as to be unavoidable, and depending on the composition of creatures, deals minor, moderate, or major bludgeoning damage to those in its path. A successful Reflex save with a DC of 20 for minor damage, DC 26 for moderate damage, or DC 34 for major damage reduces this damage by half, while a critical success avoids damage entirely.

While the stampede is always damaging, it moves in the direction of the nearest source of fresh water, spinning and twisting creatures damaged by the stampede in that direction. After dealing damage, the stampede vanishes, becoming a cloud of sand and dust that quickly settles.

Additionally, it is exposed to the titanic flytrap toxin from the hundreds of tiny hairs that line the inside of its leaves. If the flytrap’s jaws Strike was a critical success, the target takes a –2 circumstance penalty to its saving throws against this poison. At the end of each of target’s turns that it remains grabbed, the target takes 3d6 acid damage.

Critical Failure As failure, but double damage.

Vines

Source NW:NEH


Vines dangling from the canopy or hanging from trees can be used to swing from one location to another. These vines can vary in length: most are between 20 and 60 feet long, but some can be hundreds or even thousands of feet long. A creature swinging on a vine can move up to twice its speed (limited by the length of the vine) as an action by succeeding on an Acrobatics check. The DC for this check is typically equal to 1/2 the number of feet traveled by vine this round (and thus becomes more difficult the more actions used to swing), but may be more or less difficult depending on how secure the vine is, the vine’s sturdiness, whether the vine is slippery, and so forth. Jumping off a vine allows you to make an Acrobatics check to Jump with a +5 bonus, and you are considered to have a running start for the purposes of the jump. If you move adjacent to another vine as part of your jump, you may end your jump early in order to catch that vine. Failing an Acrobatics check to swing on a vine means you fall off the vine. If you hold onto a vine after beginning to swing, but do not use an action to swing, you are still carried 20 feet forward from the momentum of the vine and must succeed on an Acrobatics check as though you had traveled 20 feet to hold onto the vine. You can let go of the vine as a free action, choosing to fall from its height. When the vine has swung as far as it can (based on length, momentum, etc.) you must jump off, let go, or move in the opposite direction you started from. If you grab hold of a vine during combat, you can attempt the following action.

Vine Smash [one-action]

Environmental


You swing on a vine, moving up to your speed (if the vine allows you to do so) and slamming into another creature.

When you do, you can make an unarmed strike against the target as part of this action and add your proficiency bonus with Acrobatics to damage. The vine stops moving after you make this attack.

Warp Sand (3pp)

Source NW:NEH


Warp sand is created when a spellcaster escapes a desert hazard via teleportation magic, and occurring in two of the desert’s most dangerous aspects: quicksand and sandstorms.

If a creature encounters and becomes fully submerged in quicksand which is warp sand, it is magically transported in a burst of bright orange light, being violently expelled from a patch of quicksand elsewhere in the desert. Creatures who remain in a sandstorm made from warp sand for more than a minute are similarly transported just outside of a building within the desert where the sandstorm occurred. Because of the magical nature of warp sand, creatures transported by it often arrive in areas rich in magic, such as ancient tombs, or large cities on the borders of deserts.

Complex Hazards

Unlike a simple hazard, a complex hazard can play the part of a creature in a battle, or can be an encounter all its own. Many of the concerns with damaging effects when designing a simple hazard don’t apply when designing a complex hazard. A complex hazard can apply its damage over and over again, eventually killing its hapless victim, and isn’t intended to be a quick-to-overcome obstacle.

Complex hazards have a lot more in common with creatures than simple hazards do, and you’ll see that a complex hazard’s statistics are similar to those of a creature.

A good complex hazard often requires disabling multiple components or otherwise interacting with the encounter in some way. For instance, while the core rules’s poisoned dart gallery requires only one Thievery check to disable, the control panel is on the far end of the gallery, so a PC would need to make their way across first.

Complex hazards roll initiative and act on their turn.

Building Routines

A complex hazard has a routine each round, whether it stems from preprogrammed instructions built into a trap, instincts and residual emotions swirling around a complex haunt, or a force of nature like sinking in quicksand. Make sure to build a routine that makes sense for the hazard; an environmental lava chute that ejects lava into the area each round shouldn’t be able to seek out and precisely target only the PCs, but it might spatter random areas within range or everything within range, depending on how you describe the hazard. However, a complex haunt might be able to recognize life force and target living creatures.

If you create a hazard that can’t consistently attack the PCs (like the core rules’s blade pillar, which moves in a random direction), you can make it deadlier than normal in other ways.

The hazard should have as many actions as you feel it needs to perform its routine. If you split the routine out into several actions, you can also remove some of the hazard’s actions once partial progress is made in disabling or destroying it; this can give the PCs a feeling of progress, and it can encourage them to handle the hazard if it appears in a encounter alongside creatures.

Perilous Flash Flood Hazard 10

Source GMG

Complex Environmental

Stealth +22 (expert)


Whether made up of water rushing through the streets that sweeps up dangerous debris along the way or a less natural substance bursting free of its container, this relentless flood batters everything in its path.

Disable three DC 35 Athletics, Crafting, or Survival checks to move or construct barricades b> enough to create a shelter from the flood. While this creates a safe place to stand, creatures outside of the barricaded area may still be in danger depending on the nature and the source of the flood.


Burst Free [reaction] Trigger A creature or effect breaks the flood’s containment; Effect The hazard rolls initiative as the flood surges forth.

Routine (1 action) The flood advances forward 60 feet, crashing into all creatures within its area. Each creature must attempt a DC 30 Fortitude save as the floodwaters pummel them and pull them downstream. The amount and type of damage dealt are based on the nature of the flood, and certain types of floods impose additional effects. The turbulent waters mean creatures within the area of the flood must attempt a DC 20 Athletics check to Swim in order to move, and those who do not succeed at a check to Swim each round may drown.

Critical Success The creature takes no damage.

Success The creature takes half damage.

Failure The creature takes full damage and is moved 10 feet along with the water.

Critical Failure The creature takes double damage and is moved 20 feet along with the water.

  • Acidic Runoff This caustic flood dissolves flesh as it moves, dealing 1d12 bludgeoning damage and 1d12+8 acid damage. Additionally, it deals 2d6 persistent acid damage to creatures who critically fail their Fortitude saves.
  • Battering Waves This flood of rushing water deals 2d12+10 bludgeoning damage.
  • Repulsive Refuse This flood has picked up tainted or disease-ridden objects like sewer runoff or rotting food. It deals 2d12+8 bludgeoning damage. Each creature exposed to the flood must attempt a DC 29 Fortitude save, becoming sickened 1 on a failure or sickened 2 on a critical failure. Additionally, creatures who come into contact with the flood waters are exposed to filth fever (DC 20 Fortitude).
  • Sharp Debris The waters have picked up various objects, some of which are particularly sharp. The flood deals 1d12 bludgeoning damage and 1d12+12 piercing damage.
  • Sticky Goo The substance is particularly sticky. It deals 2d12+6 bludgeoning damage. Additionally, each creature in the flood must attempt a DC 29 Reflex save at the beginning of their turn each round. On a failed saving throw, they take a –10-foot circumstance penalty to all their Speeds for 1 round. On a critical failure, they are instead immobilized for 1 round.

Flensing Blades Hazard 12

Source GMG

Complex Haunt

Stealth +25 (expert)


A whirling tornado of spectrally propelled glass and steel slices whatever it touches to ribbons.

Disable DC 35 Thievery (master) to precisely adjust the blades so that they destroy each other, or DC 38 Religion (expert) to weaken the haunt; four successes are required to disable it AC 33; Fort +27, Ref +25, Will +22

Hardness 20; HP 100 (BT 50); Immunities critical hits, object immunities, precision damage; Weaknesses positive 15


Whirling Blades [reaction] Trigger Three or more creatures enter the area of the haunt; Effect sharp fragments lift up from the ground and begin to spin in rapid circles taking up one 5-foot square. The haunt rolls initiative.

Routine (3 actions) The tornado of blades uses 3 actions to move, traveling up to 30 feet with each action and dealing 2d10+10 slashing damage. Each creature in its path must attempt a DC 33 Reflex save.

Critical Success The creature is unaffected.

Success The creature takes half damage.

Failure The creature takes full damage plus 1d10 persistent bleed damage.

Critical Failure The creature takes double damage and 1d10 persistent bleed damage. It also becomes wounded 1 (or increases its wounded value by 1, if it is already wounded).

Each successful check to disable this hazard reduces the haunt’s movement by 30 feet, and the fourth success disables it completely.


Reset The haunt draws jagged shards back into its area over the course of an hour, after which it can trigger again.

Dance of Death Hazard 16

Source GMG

Complex Haunt

Stealth +32 (master)


An eerie orchestra compels all who hear it to dance until they collapse from exhaustion.

Disable DC 42 Intimidation (expert) three times to frighten dancers and spectral musicians alike away from participating in the deadly performance, DC 40 Performance (master) twice to produce a tune discordant enough to disrupt the compulsion, or DC 42 Religion (master) three times to banish the spirits with prayers


Prelude [reaction] (auditory, enchantment, incapacitation, occult) Trigger A creature approaches within 30 feet of the orchestra; Effect The orchestra compels all creatures that can hear it to begin dancing. Each creature must attempt a DC 41 Will save, with the following effects.

Critical Success The creature is unaffected.

Success The creature is flat-footed and cannot use reactions. Additionally, it must spend 1 of its actions each round dancing. Dancing is a move action that allows the creature to Stride up to half its Speed.

Failure As success, except the creature must spend 2 of its actions each round dancing.

Critical Failure As failure, except the creature must spend 3 of its actions each round dancing.

Routine (1 action; auditory, enchantment, incapacitation, occult) The orchestra performs a raucous tune, compelling all creatures that can hear it to spend actions dancing. Each round, creature must attempt a DC 37 Will save; the results of this save modify the number of actions that the creature must spend dancing each round. If this would cause the creature to spend more actions dancing than it can use on its turn, the creature takes 10d6 damage (or double that on a critical failure) from moving faster than its body can manage.

Critical Success The creature decreases the number of actions it must spend dancing by 1.

Success No effect.

Failure The creature increases the actions it must spend dancing by 1.

Critical Failure The creature increases the actions it must spend dancing by 2.


Reset The eerie orchestra spends an hour retuning its phantasmal instruments, after which it is ready to begin its routine again.

Vortex (3pp) Hazard 5

Source NW:NEH

Complex Environmental

Stealth +13 (trained) (or -10 and no minimum proficiency if viewed from the surface of otherwise calm water)


A whirlpool or vortex of water caused by shifts in pressure, a sinkhole, unusual rock formation, or magic drags creatures and objects into it, and buffeting them with rapidly moving water. A vortex is a cone up to 60 feet long which originates underwater and terminates on the surface of the water.

Disable Survival DC 22 to disturb the drag of the current using a large rock or similar. A creature that succeeds on a DC 22 Athletics check to Swim can escape the vortex.


Drag Down [reaction] Trigger A Small or larger creature or object moves within 5 feet of the vortex. Effect The triggering creature or object is dragged into the vortex and 5 feet down.

Routine [one-action] All creatures and objects within the vortex must succeed on a Reflex save (DC 22) or be dragged into the vortex and 5 feet down. Each creature or object then suffers an amount of damage equal to 1d6 + 1d6 for every 10 feet below the surface of the water. As the creature or object is dragged down, it moves diagonally toward the center of the cone. If multiple creatures occupy the same space in the vortex, each suffers an additional 2d6 points of bludgeoning damage as they collide over and over again; this damage is applied for each other creature sharing the same space.


Reset A vortex typically destroys obstructions which disrupt it within 10 minutes. A vortex which is permanently disrupted, for instance as the result of an earthquake, cannot be reset.
