Extort Truth

Starting at 6th level, you can precisely strike a hidden cluster of nerves on a creature, temporarily preventing it from masking its true thoughts and intent. When you hit a creature with an unarmed strike, you can spend 1 focus point to force it to make a Charisma saving throw. On a failed save, the creature is unable to speak a deliberate lie, and all Charisma checks directed at the creature are made with advantage for up to 10 minutes. You know if it succeeded or failed on its saving throw.

An affected creature is aware of the effect and can thus avoid answering questions to which it would normally respond with a lie. Such a creature can be evasive in its answers as long as the effect lasts.

If you wish to impose this effect on a creature without injuring it, you can attack the creature to simply touch it, dealing no damage on a hit.
