This free generator builds environmental hazards and traps for 5e and other tabletop roleplaying games. Each result includes a scaled difficulty class, damage, and the counterplay that lets players solve the danger instead of merely surviving it.
How to generate a trap or hazard
- Choose Hazard for an environmental complication or Trap for a constructed danger.
- Pick an Environment: Dungeon, Cavern, Wilderness, Urban, Swamp, Volcanic, Arcane, or Any.
- Set the Threat Tier to match your party: levels 1-4, 5-10, 11-16, or 17-20.
- Choose a Quantity and select Generate. Copy any result into your notes with its copy button.
Designed for fair, solvable danger
Each hazard and trap scales its difficulty classes and damage to the tier you choose, and names ways to detect, disarm, or avoid it. Place results in a room from the dungeon generator or the cavern generator, and add a reward from the treasure generator.
