Dungeon Feature Generator

What this generator does

Draws a room feature for a dungeon from banks covering different feature types, so a generated room mixes structure, hazard and detail rather than repeating one category.

What you'll get

This generator draws from a hand-checked list of 28 entries. Here is a spread of 6 of them, so you can see the style before you generate:

• A collapsed ceiling has half-buried the passage ahead.
• A door here has no handle on this side.
• An old rope ladder hangs down from a hole in the ceiling.
• The stairs down have been deliberately broken, from this side.
• A chalk line runs along the floor and stops at a closed door.
• Roots have forced their way through the ceiling, though this is far underground.

A fixed sample of the list, not a live draw — your own results are picked at random from all 28, without repeating until the list runs out. Original HEKNO-curated system-agnostic dungeon feature list. Last reviewed 2026-09-03.

How to use this tool

1. Press generate for a new feature.
2. Generate again any time for another one.

Common use cases

• Adding texture to an otherwise empty room
• Game master improvisation
• Session prep for dungeon crawls

Limitations and good to know

• Features are prompts for a games master to interpret, not balanced encounters. Nothing here accounts for party level or system rules.
