Lie Detector Feat 4

Investigator​
Source Pathfinder Player Core 2
Prerequisites empiricism or interrogation methodology

You're adept at noticing the tells of a liar—sweat, flushing, a quavering voice, a quickening pulse. You gain a +1 circumstance bonus to Perception checks to Sense Motive and to Perception DCs against attempts to Lie to you. When you determine someone is lying to you, you can use their deceit to your advantage to gain a +1 circumstance bonus to the next Deception, Diplomacy, Intimidation, or Performance check you attempt against that creature within the next minute.

If you would gain your Pursue a Lead investigation bonus to any of the above checks, that bonus increases by 1 instead of you gaining the +1 bonus listed.
