Pièges
- "'Oups'. C'est le dernier mot que je souhaite entendre à l'intérieur d'un de ces pièges mortels. 'Oops' signifie que quelque chose vient de se passer horriblement, probablement mortellement, de travers. Il y a mille façons différentes de mourir dans l'un de ces puits perdus, et lorsqu'il s'agit de risquer sa peau pour s'emparer des trésors les plus fantastiques que ces jungles ont à cacher, je vous le dis tout de suite, il n'y a pas de place pour les "oops" dans mon expédition. Et vous pouvez tous parier vos actions sur une chose : si votre 'oops' ne vous tue pas, je suis sûr que je le ferai."

machinations and deathtraps imagined in fiction and film. The best traps prove to be more than mere hindrances or cheap “save-or-take-damage” annoyances. Whether they’re elaborate puzzles testing their victims’ cunning or multipart murderers forcing their prey to think quickly to escape certain doom, well-crafted traps can produce encounters just as memorable as any narrowly won combat.
Presented herein are a host of new traps ready for use as part of the Serpent Skull Adventure Path or in any campaign. While those on this page expand on the list of sample traps found in Chapter 13 of the Core Rulebook, the pages that follow expand upon the works of kobold trapsmiths, ancient tomb guardians, and madmen with a knack for mechanical engineering, providing maniacal masterworks sure to test even the wariest adventurers. In the descriptions of these traps, elements with specific trap stat blocks are listed in quotation marks, such as with the “pendulous staircase” or “ignited philosopher’s stone.”[1]
beyOnd The basIcs
Both versatile and lethal, these simple traps expand upon the low-level traps in the Core Rulebook and can be utilized in any manner of adventure, from wilderness explorations to high-stakes tomb robberies. The rules for the drag and dirty trick combat maneuvers are presented on pages 320–321 of the Pathfinder RPG Advanced Player’s Guide. GMs seeking even greater variety might choose to alter the types of damage their traps deal or customize cosmetic elements to tie their effects more closely to the traps’ surroundings. A poison dart trap that shoots miniature fangs or a summon monster VI trap that conjures dozens of snakes proves much more thematically appropriate to adventures like those found in the Serpent Skull Adventure Path than the generic standbys.[1]

The dOuble deaTh
A new take on an old trap, the double death is, at its most basic level, a wide pit trap. Yet those who fall prey to the trap not only find themselves victims, but also bait that attracts their companions to an even deadlier doom. This trap is best suited to characters of levels 8 to 10.
The Trap: A two-level pit trap surrounded by tiles that collapse into a slide. After the first pit trap is triggered, the second gives way a moment later, spilling those trapped down to a spiky doom.
How It Works: As creatures near the brazier, the first part of the trap is sprung, with the f loor dropping away as soon as 150 pounds of weight enter the squares immediately surrounding the fixture. This functions just as a standard pit trap, dropping victims 15 feet, as described in the “upper pit.” Unseen from the surface, the collapse of the first pit trap sets off a secondary mechanism that requires 2 rounds to activate. At the end of these rounds, the edges of the open pit collapse into steep slides, potentially spilling anyone at the pit’s lip into the pit. At the same time, the f loor of the upper pit collapses, spilling its contents another 20 feet into the spear-lined depths. The dropping away of the false f loor creates a slight lip that the most agile victims might be able to cling onto to prevent themselves from falling, but such a miraculous save proves difficult at best.
Upper Pit CR 4
Type mechanical; Perception DC 26; Disable Device DC 20
Effects

Effect 15-ft.-deep pit (1d6 falling damage); DC 20 Reflex avoids; multiple targets (all within a 20-ft.-square area)
Lower Pit CR 12
Type mechanical; Perception DC 26; Disable Device DC 20
Effects
Trigger location; Reset manual
Effect 20-ft.-deep pit from upper pit (2d6 falling damage) or 35-ft.-deep pit from top (3d6); pit spikes (Atk +15 melee, 1d4 spikes per target for 1d6+5 damage each); DC 24 Reflex from upper pit or 22 Reflex from top; multiple targets (all in pit and within 5 feet of its edge)[1]
pendulOus sTaIrcase
A sort of double trap, the pendulous staircase menaces those who tread too heavily upon its fragile steps, threatening to crush climbers like a gigantic pendulum, but also leaving them stranded amid whatever dungeon depth they seek to escape. The Trap: A huge but loose length of chain supports this stairway. While it is strong enough to support the stairs and considerable additional burdens, the stairs maintain their position by relying upon fragile moorings fastened into the cylindrical well. As passersby tread upon the stairs, they potentially break these moorings, causing the stairs to sway. As the central column becomes less fixed in place, it crashes against the walls, crushing climbers or sending them careening into the depths.
How It Works: This spiral staircase consists of a central pillar in a 90-foot-deep shaft. Stone steps connect the central pillar to the walls of the shaft. These steps fit into shallow slots cut into the wall. Characters who descend the staircase to the bottom discover a gap between the last step and the f loor of the lower chamber. Among these stairs, spaced approximately 15 feet apart, are several steps deliberately designed to break. These false steps appear nearly identical to the solid steps, though a DC 25 Perception check notices the almost imperceptible cracks. A character who steps on a “breakaway stair” risks falling through the broken tread and falling down to the next twist of the spiral staircase.
Once a step had broken away, any contact with the stairs sets the whole central column swinging. Each round, all characters on the steps must make a Ref lex save to avoid the “pendulous staircase.” The DC of this Ref lex save increases by 1 for every one of the 14 breakaway stairs that is broken. If a character fails her Ref lex save, roll 1d20 and add the number of stairs broken, then reference the Pendulous Staircase Effects chart to determine how the stairs’ movement imperils the character.

phIlOsOpher’s sTOne
Alchemy is the art of turning lead into gold, the base into the sublime, the physical into the spiritual. Also, it is the art of making things explode.
The Trap: A giant metal boulder filled with volatile chemicals careens down a hall, then back again, possibly lodging in the narrow passage. Alcoves line the hall, potentially giving those in the boulder’s path shelter, but interconnected spring systems behind the statues within mean that pushing a sculpture in on one side of the hall pushes those on the other side out, forcing those seeking refuge in the alcoves across the hall into the path of the thundering boulder.
How It Works: Two components make up this trap: a giant metal boulder filled with volatile chemicals (the philosopher’s stone); and twin sets of “tethered statues” lining each side of the hall.
Philosopher’s Stone: The philosopher’s stone reprises the classic runaway boulder trap with an alchemical spin. A 15-by-10-foot pressure plate fills the centermost length of a lengthy corridor. After the trap is set off with an audible click, the philosopher’s stone begins rolling. The PCs have 1 round to react to the boulder rolling down the ramp. After the first round, the jostling of chemicals within the stone causes it to light, propelling the “ignited philosopher’s stone” by its internal explosions like a Catherine wheel firework. Sparks shoot out of the boulder, sending it spinning forward. Creatures that didn’t manage to escape the lower hall in
the round before the philosopher’s stone ignites must save versus the “ignited philosopher’s stone.” The stone bowls over any creatures of Medium size or smaller that it strikes and continues moving. Creature of Large size or greater halt the movement of the stone, but take double damage from the trap. Magic that creates solid barriers—like interposing hand or the various wall spells—can halt the stone, though the violent thrust of telekinesis or a ring of the ram merely jars the boulder. A creature can attempt to halt the philosopher’s stone by physical force, but it must make a DC 30 Strength check and is struck by the trap without receiving a saving throw. Those who succeed at this Strength check halt the boulder, while those who fail are bowled over as normal.
The philosopher’s stone has enough momentum to roll down the hall once, ascend halfway up the ramp on the far side of the passage, and—1 round after its initial roll through the hall—barrel back through the passage before coming to a rest not far from the bottom of the ramp it initially hurtled down. After losing its momentum, the stone stops expelling chemical fire but still blocks the hall. Creatures of Medium size or smaller can squeeze past, though the “blocking boulder” is still covered in caustic chemicals and might roll to crush those who try to slip around it. The boulder can be moved with a DC 24 Strength check, though any creature that voluntarily touches it takes 1d6 points of acid damage. It can also be destroyed, though this requires some effort (the thick steel ball has hardness 10 and 1,800 hit points).
Statues: The PCs have 1 round of warning before the philosopher’s stone bowls down the hall, and a second round in which to react before it makes its second pass. Those in the corridor who make a DC 26 Perception check notice that the statues in the hall’s alcoves are on plates with small rollers and have spring mechanisms affixed to their backs. Any creature that makes a DC 20 Strength check can force a statue deeper into its alcove, creating a spot for a Medium or smaller creature to stand that is safe from the philosopher’s stone’s burning rampage. The mechanisms attached to the “tethered statues” are more than mere springs, though. Any creature that pushes a statue deeper into a wall causes all three statues on that side of the hall to slide back, thus opening not one, but three 5-foot-square alcoves on that side of the hall.
At the same time, with the same amount of Strength that the creature pushing back a statue exerted, the three statues on the other side of the hall slide out. If two creatures on opposite sides of the hall attempt to push statues into the alcoves in the same round, both must make opposed Strength checks to see who succeeds in pushing back the statues—the victor pushes his way to safe shelter, while the loser is forced into the hall. The shapes of the “tethered statues” are such that they never slide fully into the hallway—or into the path of the philosopher’s stone. If multiple creatures seek shelter by pushing back statues on the same side of the hall, the boulder can pass them by without harm, while those who seek opposing shelters face a startling tug-of-war with a swift and deadly result.

Water is the bane of many adventuring parties, typically for the tentacled terrors and coiling serpents found within. But sometimes, water proves deadly enough by itself. The Trap: Water pressure prevents a rusted iron door from opening while the pool it rests within stands full. Two pillars support the ceiling directly over the water, their foundations composed of highly buoyant material forced into a stationary position at the tops of water-filled pipes beneath the pool’s f loor. A valve opposite the door opens drains beneath the room. As the water in the room and the pipes drains out, the speed of the drainage causes the pillars to descend at a rate faster than the water in the pool, potentially trapping and crushing creatures in the pool.
How It Works: A rusted iron door stands at the bottom of a 15-foot-deep pool of water. The door has hardness 10, 120 hit points, and a break DC of 35 due to the water pressure aiding in holding it closed. The added hindrances of moving and attacking underwater make reaching or destroying the door difficult (see page 432 of the Core Rulebook). Fortunately, a valve opposite the door opens drains in the f loor, allowing the water to flow out—with deadly side effects.
Those who succeed on a DC 22 Perception check notice the f loor of the pool contains a circular pattern of holes at its center, as if it were the subtle opening to a large drain. A DC 28 Perception check also notices very tight gaps around the bases of the twin pillars rising between the pool and ceiling. Any creature that succeeds on a DC 16 Perception check also notices a wheel-shaped valve at the pool’s bottom, and upon reaching it can employ it with a DC 20 Strength check. The valve only works in one direction, opening drains hidden in the pool’s f loor, but possessing no ability to close them. Once these drains are open, three pipes begin draining water out of the room: two steadily lowering the water beneath the pillars and one slowly draining the pool itself.
As the pillars are affixed to a buoyant material held aloft by the water in the room, and those pillars in turn support the ceiling, draining the water below them causes the ceiling to begin lowering at a rate of 5 feet per round. The slow drainage of the pool also causes the water level to drop at a rate of 5 feet every 2 rounds. Creatures in the pool thus have 2 rounds to escape the pool before the ceiling reaches a point that it traps them in the pool’s basin, and another 3 rounds after that before the ceiling of the “crushing pool” slams down upon them. The ceiling could potentially be destroyed, but it has hardness 8 and 760 hit points. Creatures trapped beneath the ceiling after it collapses fully take 1d6 points of nonlethal damage every round as if they were buried by a cave-in (Core Rulebook 415).
The door is recessed enough that it can be manipulated after the ceiling descends and the water drains out of the room—reducing its Break DC to 25.

TerrIble ThurIble
Bane of overzealous thieves, this trap grows worse by the moment, though a simple sacrifice at the right moment might save others from choking death and whirling f lames. This trap is best suited for characters of levels 6 to 8.
The Trap: Tampering with the chests releases the thurible hanging against the wall, a container filled with black powder and poison. If allowed to swing across the room, it ignites upon coming in contact with the statue’s firepot. The shape of the thurible, the f lexible cord, and the exploding powders within the heavy container inside send the thurible reeling around the room, striking those within as it spreads f lame and toxic dust.
How It Works: The lids of the chests in this room are connected to mechanisms in the f loors and walls connecting to the hanging thurible. Those who investigate the chests can discover a simple switch in either with a DC 26 Perception check, though the device obviously doesn’t connect to anything deadly within the chest. Those who investigate the hanging thurible can make Perception checks at the same DC to detect an equally simple clasping device attaching it to the wall.
Should the chest lids be lifted, the switches are triggered, causing the heavy thurible hanging on the wall to unclasp and swing down. Any creature in the 10 squares directly between the “swinging thurible” and the statue are attacked as noted below. The attack is slow and easy to avoid, but still packs something of a punch. If it strikes a creature in its f light, it deals damage as noted and the impact causes it to stop moving, circumventing the trap’s other dangers.
If no creatures block the way between the thurible and the statue, or if it misses them, the thurible swings to the extent of its cord, pausing over the open f lame. This causes the alchemical mixture within the container to erupt violently into f lames, turning the metal pendulum into a “lit thurible” that begins spinning about the room. The cord holding the f laming sphere is elastic enough to erratically bounce and swing the thurible with the force of a bludgeon, making any creature in the room a target for its bounding f light. At the same time, the f laming thurible expels doses of deadly ungol dust, exposing everyone in the room.
The thurible has enough explosive powder and ungol dust to be a threat for 3 rounds, after which its swinging slows and it gradually comes to rest at the room’s center. The chests can be investigated in safety at this point; their contents are left to the GM to decide.[1]
