A trap chest is a type of booby trap disguised as a chest, often found in video games and other fictional settings. They are typically activated when the chest is opened, triggering a hidden mechanism that can cause a variety of harmful effects, such as releasing poisonous gas, launching projectiles, or summoning monsters.
Trap chests can be a hazard to adventurers, but they can also be used to protect valuable items or to deter unwelcome visitors. In some cases, trap chests may even be used as a form of entertainment, providing a challenge for players to overcome.
