Over the last 30 years, I’ve collected a shortlist of my favorite traps in Dungeons and Dragons (DND). These traps work great for both beginners and more advanced Dungeon Masters.
In this guide, you’ll learn the best and most creative DND traps to enthrall, amaze, and impress your players forever.
What are the best DND traps?
Here Are The 21 Best DND Traps
The best DND Traps match the difficulty and potential danger to the experience level of the player group. DND traps inflict damage, shift attention, and make the game more fun. Unique and creative traps include mechanical, magical, or monster-based traps.
For each of these traps, you’ll get an explanation, tips for how to use it during a game, examples, and a good description of the trap you can use.
These traps can be used for damage, distraction, or dynamics:
- Damage – Handicap or injure the party
- Distraction – Slow down or divert attention
- Dynamics – Fun and excitement
Without further ado, here is the list of the best DND traps for devious DMs.
Trap 1: Magnetic Walls
Magnetic Walls trap players by manipulating the magnetic fields in the room, causing them to become stuck to the walls or ceiling.
Tips for Using this Trap:
- Use this trap to split up the party or to create a dangerous obstacle course.
- Provide the players with a way to disarm or bypass the trap, such as by finding a hidden switch or using a non-magnetic object as a shield.
- Add additional enemies or hazards to make the trap more challenging. For example, a giant rat or spikes.
Introducing the Trap:
As the players move through the dungeon, they hear a low hum in the air.
Suddenly, they feel a strange force pulling them toward the walls. As they try to move, they realize they’re becoming stuck to the walls, ceiling, or floor.
“You’re stuck fast to the magnetic walls!” you say. “What do you do?”
Alternate Ways to Use the Trap:
- For lower level groups, make the magnetism weaker, so the players can still move, but with a penalty to their speed.
- For higher-level groups, make the magnetism stronger, causing the players to take damage if they try to pull away.
Trap 2: False Treasure Room
The False Treasure Room is a trap that baits players with the promise of treasure, only to trap them when they try to take it.
Tips for Using this Trap:
- Use this trap to tempt players with the promise of treasure, but make it clear that it might be too good to be true.
- Give the players a way to get around the trap, such as by using a detect magic spell to reveal the illusion.
- Increase the challenge of this trap with added hazards or enemies. Perhaps you can add an acid-spewing ooze in the trapped room or a slowly crumbling floor like in a video game.
Introducing the Trap:
As the players enter the room, they see a glittering pile of treasure in the center.
“You see a pile of gold and jewels, sparkling in the light,” you say. “It looks too good to be true.” When the players approach the treasure, they trigger the trap and become trapped.
“The treasure was just an illusion,” you say. “Now you’re stuck in the room. What do you do?”
Alternate Ways to Use the Trap:
- For lower-level groups, make the illusion weaker, so it’s easier to see through.

Here is a good video with their version of the best DND traps:
Best DND Traps By Player Level
To put this all together, I made a chart to help you choose the perfect DND trap for your players.
By using the chart, you’ll be able to match the best DND traps to:
- The level of your players
- The unruliness of your players
Honestly, this chart has been an amazing help in my games. I hope it helps you just as much:
| Trap | Beginner Players | Experienced Players |
|---|---|---|
| Magnetic Walls | ✓ | ✓ |
| False Treasure Room | ✓ | ✓ |
| Haunted Armor | ✓ | ✓ |
| Giant Rolling Boulder | ✓ | |
| Anti-Gravity Room | ✓ | ✓ |
| Riddle Door | ✓ | ✓ |
| Room Full of Mimics | ✓ | |
| Crystal Shards | ✓ | |
| False Floor | ✓ | ✓ |
| Fire Room | ✓ | |
| Time Warp Room | ✓ | ✓ |
| Crushing Ceiling | ✓ | ✓ |
| Net Trap | ✓ | ✓ |
| Illusory Wall | ✓ | ✓ |
| Invisible Bridge | ✓ | ✓ |
| Pressure Plate | ✓ | ✓ |
| Poison Gas | ✓ | |
| Mystery Maze | ✓ | ✓ |
| Slippery Surface | ✓ | ✓ |
| Monster Chute | ✓ | |
| Explosive Runes | ✓ |
Notes:
- Beginner players are new to DND and may need simpler traps to understand and overcome.
- Experienced players are more familiar with DND and may require more challenging and complex traps to keep the game interesting.
- One idea I really like is to create a “SAW” movie-esque dungeon with traps like the “Eye Opener” and “Retrieve Key Inside a Corpse.”
Final Thoughts: Best DND Traps
The level of player unruliness can also affect which traps to use, as more unruly players may require traps with higher consequences or more dangerous hazards.
