The Player’s Handbook describes common hazards that adventurers encounter, such as falling and dehydration. This section details some unusual hazards you can add to a location to make it more challenging.
Each hazard in this section is designated as a nuisance or as deadly for characters of certain levels. A nuisance hazard is unlikely to seriously harm characters of the indicated levels, whereas a deadly hazard can grievously damage characters of the indicated levels.
Use caution when introducing a hazard to characters of a level lower than the hazard’s level range. A hazard that is a nuisance at one level range could be deadly to characters in the next-lower range.
Hazards are presented in alphabetical order.
