Sense Motive

By watching someone’s body language, listening to them speak, and appraising how they react to what’s around them, you attempt to understand their mental state and specifically whether they’re being truthful or concealing something.

Make a Perception check against the Will or Deception DC (whichever is higher) of the target. If your target is a noble or a criminal, you can use Society Lore or Underworld Lore instead, respectively.

You can perform this action only once on a given target for every five minutes of conversing or dealing with it. The GM may allow you to roll more often than this if the target loses its composure or otherwise stops being able to deceive or mislead you for some reason.
