Random Dungeon Generator

Looking for a full map? Try the Dungeon Map Generator

Randomly generate parts of a dungeon on the fly, pieces are modular and fit together so you can even generate an entire dungeon this way. If you're generating from scratch, begin with a starting area and then add random doors and passages. Passages can connect to other passages, and should continue to be generated until they're all linked to doors, rooms, or dead-ends. Refresh to generate new things. You can also drag and drop pieces onto the grid map to build as you go.

Contents

Monster

Each monster should have a motivation in the dungeon. Sometimes this might make them peaceful (even if temporarily).

Motivation: Hide from enemies
Personality: Brave; stands its ground.

Random Hazards

Hazard: Violet fungus: This purplish mushroom uses root-like feelers growing from its base to creep across cavern floors. The four stalks protruding from a violet fungi's central mass are used to lash out at prey, rotting flesh with the slightest touch. Any creature killed by a violet fungus decomposes rapidly. A new violet fungus sprouts from the moldering corpse, growing to full size in 2d6 days.

Random Obstacles

Obstacles block or hamper progress and can affect more than one room.

Obstacle: Overgrown mushrooms block progress and must be hacked down (25 percent chance of a mold or fungus dungeon hazard hidden among them)

Random Traps

Random Tricks

Tricks are quirky and less deadly than a trap. Some tricks are permanent, others can be dispelled with Dispel Magic.
