You know when others lie.
Prerequisites
Wisdom 13.
Benefit
As long as you maintain psionic focus, you gain a +2 psionic bonus on Insight checks.
You may also expend your psionic focus to gain a +10 psionic bonus on an Insight check to oppose a Deception check. You must decide whether or not to use this feat prior to making an Insight check. If your check fails, or if the opponent isn’t lying, you still expend your psionic focus.
