From Dragon Quest Wiki

Pitfall is an ability in the Dragon Quest series. It digs a trap on the world map to snare the unwary.


Dragon Quest IX: Sentinels of the Starry Skies[edit]

This ability is learned with 22 skill points allocated into Acquisitiveness skill.

While the skill may seem next to useless in single-player mode (the skill can trap monsters, but requires extreme precision), it sees much use among pranksters in multiplayer mode. Heroes can joke around with friends by placing pitfalls right outside doorways, or under the friend while they are occupied with a menu or in-game conversation. However, would-be jokers should be aware that they can fall into their own pitfall.
