A Collection of Traps & Hazards (D&D 5e)

The world your players are exploring should be filled with dangers other than monsters. This week on the Campaign Trail I wanted to share some traps and hazards I have used in my campaigns. The D&D 5th edition Dungeon Master Guide and the published adventures provide us with a limited number of traps and hazards, but I thought this collection might be interesting too. Some of these I have included in previous articles, but I thought collecting them in one place would be handy.

What are Traps and Hazards?

A trap is commonly found in a dungeon, but can be set along a forest path, in a home protecting valuables or anywhere. Traps should serve a purpose such as preventing intruders from progressing, protecting treasure or hunting. Traps can be mechanical or magical, so you should also think about who would have set the trap and why when placing it in your adventure. If you have a rogue with high perception who finds all your traps, try a magical trap.

A hazard is a location based threat that is similar to a trap.

  • Natural hazards present players with survival challenges as the environment itself is trying to kill them such as floods, landslides, and cave-ins.
  • A living hazard is different from a monster as it usually can’t do much more than mess with the players somehow like a fungi releasing spores.
  • Magical hazards (or technological hazards such as radiation) are often leftover effects from spells or experiments gone wrong.

Example Traps and Hazards


I looked to Pathfinder’s Core Rulebook for some ideas on how to use quicksand in my D&D 5e game.

Type: Hazard
Environments: Jungle

A patch of quicksand will usually appear solid and might even be covered with debris. An adventurer who is traveling at normal pace (not running) should be given a DC 15 Wisdom (Survival) check, which is enough to recognize the danger. A running creature will not be given a save and travel 5′-10′ into the pit (roll 1d2 x 5′). A typical quicksand pit should be around 20′ in diameter.

Creatures in quicksand need to make a DC15 Strength (Athletics) swim check to move 5 feet (in any direction), failure results in sinking 5′ and beginning to drown. You may want to allow close fails of 4 or less to float where they are. A creature whose head falls beneath the surface of quicksand will need to succeed on a swim check to get to closer to the surface or be rescued, otherwise see drowning rules.

Tar Pit

Similar to quicksand, but with fire! You can make minor tweaks to quicksand to also create stink bogs and horse swallowing muck.

Type: Hazard
Environments: Jungle

Tar pits can often be found scattered throughout the jungle or ruins. They would appear as nothing more than a shallow pond, but a DC 13 Wisdom (Survival) check is enough to recognize the danger. A tar pit functions as quicksand and ignites if brought into contact with open flame.

Brush Fire

Type: Hazard
Environments: Grassland

Placing standard traps in a grassland setting can work, but a pit trap does not make as much sense in the middle of a field as on a trail or in a dungeon. Having your adventurers face a brush fire can be used to create a challenge or to steer your players away or towards a goal. As the fire catches the adventurers with its flames and smoke, have them make a DC 13 Constitution check  to see if they are overcome by the fire (or whatever is appropriate to your player’s escape actions). Anyone who gets caught takes 1d6 fire damage; as the fire spreads, anyone who starts their turn in the area or moves through it takes 1d6 fire damage; eventually, smoke causes obscurement and then suffocation. You could even try out the chase rules in the Dungeon Master Guide where the players are the quarry. For bonus DM points consider the direction of the wind as a factor in the movement of the fire, even having it pick up to create a deadly firestorm.

Room of Pacification

This is a silly hazard that I used in an Adventure Time game. It might fit your game, but proceed with caution if you use it.

Type: Trap
Environments: Dungeon

This trap is activated when an intruder enters a room. A statue shoots out a violent beam of magical energy any time a creature does too much, as in anything more than simply walking (or moving at base flying speed for floating or flying creatures). The statue should be a representation of something lazy like a sleeping animal, but have something to tempt your adventurers like a huge gem on its chest. You might even have a warning for the players to “Relax” or “Take it easy”.

A spell or other effect that can sense the presence of magic, such as detect magic, reveals an aura of evocation magic around the statue. A successful dispel magic (DC 13) cast on the statue disables the trap for 24 hours.

When the trap is activated it causes the statue to shoot out a beam of magical energy, the triggering creature must make a DC 13 Dexterity saving throw, taking 11 (2d10) force damage on a failed save, or half as much damage on a successful one.

Jiggly Jelly Floor

This is a silly hazard that I used in an Adventure Time game. It might fit your game, but proceed with caution if you use it.

Type: Trap
Environments: Dungeon

The floor in this room (with a minimum 20 foot ceiling) is jiggly. Movement across the room sends nearby creatures bouncing into the air. A successful Intelligence (Investigation) or Intelligence (Arcana) check (DC 15) will grant knowledge of how the jelly floor acts. A Wisdom (Perception) check (DC 15) is required to notice the jelly floor.

The floor feels like hard stone when lightly touched touch, but while walking across the floor or if hit, it really jiggles. A creature on the floor who is within 5 feet of another creature who is walking across the floor (or hits the with a decent amount of force) is tossed 10 feet into the air and takes 1d6 bludgeoning damage.

Drowsy Daisies

This is another hazard from the Adventure Time. It could work well if you are exploring woods with fairy magic. I modified this slightly when my players were deep underground and meet up with some fungi.

Type: Hazard
Environments: Forest Meadow

Your adventurers see a shimmering field of daisies growing in front of them, filling them with with a pleasant feeling of peace and tranquility if they can smell them. A creature exposed to this field for longer than 1 minute must succeed on a DC 15 Wisdom saving throw. If it fails its saving throw, it is charmed and will bend over or sit down to do nothing else but smell the beautiful flowers.

At the end of of each of its turns, an affected creature can make a Wisdom saving throw. If it succeeds, this effect ends for that target. If the creature continues to smell the flowers for 1 minute it will fall asleep.

Knife Storm

Another hazard from the Adventure Time. It could work well if you want to move your players along or have them look for cover, finding the next adventure location.

Type: Hazard
Environments: Outside

The skies grow dark as black clouds roll in from the west. The knife storm will be here in 1 minute. Basically run and find shelter or start to dodge daggers.

No check is required to notice the storm. A successful Intelligence (Nature) check (DC 15) to predict that the distant storm clouds are actually a knife storm that will arrive in 1 minute. Anyone who has experienced a knife storm before has Advantage on the check.

Suddenly, the first “drop” falls; a perfectly formed iron dagger. Any creatures caught out in the open in a knife storm will be the target of 2 knives each round. Each knife makes a ranged attack with a +5 bonus against a random target. Any cover such as trees, shields held overhead or other portable cover should be considered using the Cover rules. A target that is hit takes 2 (1d4) piercing damage.

Huge Wall or Trench

Let your PCs be like Matt Damon in The Great Wall or hold back the north like in Game of Thrones.

Type: Hazard
Environments: Grassland

Place a long wall or wide trench in the middle of a grassland. Trenches are often dug by soldiers for protection during war, but they can be used to keep away monsters. A tall wall stretching forever in either direction could be found or a wall that is clearly created as a powerful fence. A trench or wall will provide your adventurers with an obstacle to overcome, but they might want to consider what is the wall or trench keeping out or in.


Type: Hazard
Environments: Any

As your adventurers travel across a large plain, a huge army appears on the top of the nearest ridge and then another army advances out of the hills on the opposite side of the plain. Effectively surrounded, it looks like your adventurers have stumbled into the middle of a battle that is about to begin. Do your adventurers try to fight everyone, quickly join a side or run? Instead of some random encounter with no impact, their choice can set off events to power an entire campaign. The armies can be led by rival orc chiefs, human kings fighting for territory, rival groups of treants or whatever you like. The more alike you make the armies, the harder it will be to choose a side for the adventurers.

A Deep Chasm

Type: Hazard
Environments: Any (or Mountain)

This dungeon is guarded by the fact that it is hard to get down to and hard to find. Assuming they arrive during daylight.

After traveling for a few hours through light forest and meadows, you arrive at the edge of the deep chasm, which splits the forest in two. Looking over the edge you see the light swallowed in darkness hundreds of feet below.

The PCs will have to climb down a deep, steep sided chasm full of ruins using their climbing gear they hopefully purchased in town. This could be run as a skill challenge or just with some tough ability checks. Reward players for using climbing gear or magic to make it easier with advantage and lower Difficulty Checks (DCs).

Climbing down the side of the cliffs should be a multi-stage challenge (2 to 3). At each stage roll for a random encounter with a 20% chance for encountering flying creatures (or put them up against creatures hidden in cliff side burrows as an alternative). Punish the players for failing the stage climb as a group with a level of exhaustion or lost hit points.

This can easily be reversed for the climb out or to climb a steep cliff.

That’s all for this week. Let me know what you think in the comments below OR even better share your own traps and hazards.
