You know when others lie.
Prerequisite: Wis 13.
Benefit: To use this feat, you must expend your psionic focus (see Concentration skill description). You gain a +10 bonus on a Sense Motive check to oppose a Bluff check.
You must decide whether or not to use this feat prior to making a Sense Motive check. If your check fails, or if the opponent isn't lying, you still expend your psionic focus.
