Oath of Law/8th Level

You and any creature within 5 meters of you must make a contested Will check if they try to deceive or lie. On a fail, a creature can't speak the deliberate lie, and can't tell a lie for 1 minute. You know if a creature succeeds or fails.
- An affected creature is aware of the aura only if they fail, and can thus avoid answering questions to which it would normally respond with a lie.
