Dungeons can be dangerous places, but it isn't just monsters, intelligent creatures and traps that make them dangerous. There can be a whole host of hazards that can affect characters, from environmental to disease to dangerous substances.
This supplement has 100 different hazards that could affect players. They are typically non-magical in nature and, whilst a few involve creatures, most do not. Many of the hazards are not hazardous at all, unless the characters tamper with them in some way.

Here are some sample results:
Maze: The area is a maze made with metal walls. The passages are tight and the joins where the metal walls meet are sharp.
Metal Plates: Square plates of metal dot the floor. Each plate is extremely hot, causing burn damage if stepped on. Metal footwear will not help.
Methane: A pocket of methane from decomposition has formed here. If naked flames are used in the area, it will explode.
Monster Corpse: The decaying body of a monster is being eaten by very aggressive parasites who will attack any creature that disturbs their meal.
Moss: Extremely damp moss covers the floor thickly, making it very slippery.
One page is the front cover, one the front matter and half a page is ads.
The supplement is also available in a version for the Pathfinder Roleplaying Game, which has Pathfinder stats for all of the hazards. You do not need both versions.
