Listen Skill

Check
Your Listen check is either made against a DC that reflects how quiet the noise is that you might hear.

In the case of people trying to be quiet, the DCs given on the table could be replaced by Move Silently checks, in which case the indicated DC would be their average check result.

Epic Check
You can pinpoint the location of an invisible creature, or detect an illusion with an auditory component.

Defeat Illusion
You can automatically detect any illusion with an auditory component for what it truly is.

Action
Varies. Every time you have a chance to hear something in a reactive manner (such as when someone makes a noise or you move into a new area), you can make a Listen check without using an action. Trying to hear something you failed to hear previously is a movement action.

Try Again
Yes. You can try to hear something that you failed to hear previously with no penalty.

Special
When several characters are listening to the same thing, a single 1d20 roll can be used for all the individuals’ Listen checks.

A sleeping character may make Listen checks at a –10 penalty. A successful check awakens the sleeper.

A character can use Listen to notice the presence of an invisible creature. If the character beats the DC by 20 or more, he or she can pinpoint the location of the invisible unit.
