Sense Motive (Skill)

Sense Motive is a Charisma-based skill that represents your ability to understands another creature's motivations as well as determine if any statement they make is a lie.

Detecting Lies
Sense Motive can be used to detect lies when a target is speaking. This may be done at any point by making a Sense Motive check versus DC (10+Target's Bluff Skill Bonus). If successful, you know whether the target believes the statement they made to be false. If unsuccessful, you have a 25% chance of being told the target believes the statement to be false, and a 75% chance of being told the target believes the statement to be true. For the duration of the encounter with the target, subsequent attempts at Detecting Lies use your previous check result.

Sensing Motivation
Using sense motivation on a target requires you to be communicating with the target for at least 30 minutes. Communicating with a target in this manner is mutual and allows the target to sense motivation on you as well. You may reduce this time to only 1 minute by taking a -10 penalty. A sense motivation check is made against the target's Social Defense. If you succeed, you may ask any one of the following questions:
 * What does the target want me to do?
 * What does the target want to do?
