Perception's checks are based on the Intelligence ability score.

Make a Perception check to notice clues, detect secret doors, spot imminent dangers, find traps, follow tracks, listen for sounds behind a closed door, or locate hidden objects.

This skill is used against another creature’s Stealth check or against a DC set by the DM. In most situations, the DM uses your passive Perception check result to determine if you notice a clue or an imminent danger.

Perception: No action required—either you notice something or you don’t. Your DM usually uses your passive Perception check result. If you want to use the skill actively, you need to take a minor action or spend 1 minute listening or searching, depending on the task.

  • Opposed Check: Perception vs. Stealth when trying to spot or hear a creature using Stealth. Your check might be modified by distance or if you’re listening through a door or a wall (see the table).
  • DC: See the table for DCs when you’re trying to hear or spot something, searching an area, or looking for tracks.
  • Success: You spot or hear something.
  • Failure: You can’t try again unless circumstances change.
  • Searching: When actively searching an area or looking for something specific, assume you’re searching each adjacent square. The DM might allow you to do this as a standard action, but usually searching requires at least 1 minute.
