Sense Motive (Wis)
Check: A successful check allows the character to avoid being bluffed (see the Bluff skill). Sense Motive does not, however, allow a character to determine whether a given statement is a lie. The character can also use the skill to tell when someone is behaving oddly or to assess someone’s trustworthiness. In addition, a character can use this skill to make an assessment of a social situation. With a successful check (DC 20), the character can get the feeling from another’s behavior that something is wrong. Also, the character can get the feeling that someone is trustworthy and honorable.
A character can use Sense Motive to detect that a hidden message is being transmitted via the Bluff skill (DC equal to the bluff check result of the sender). If the character’s check result beats the DC by 5 or more, the character understands the secret message as well. If the character’s check fails by 5 or more, the character misinterprets the message in some fashion.
Time: A Sense Motive check may be made as a reaction to another character’s Bluff check. (When that’s the case, the GM may roll the character’s Sense Motive check in secret, so the character doesn’t necessarily know someone’s trying to bluff him or her.) Using Sense Motive to get a sense of someone’s trustworthiness takes at least 1 minute.
