Court of Candor

You create an atmosphere in which deception becomes extraordinarily difficult.

Creatures of your choice in the emanation must make a Charisma saving throw when they enter it for the first time or start their turn there.

On a failed save, a creature can't knowingly speak a direct falsehood while inside the emanation.

Unlike similar truth magic, Court of Candor also causes deliberate evasions to become apparent. Whenever an affected creature intentionally answers a question in a misleading manner while technically avoiding a lie, creatures hearing the statement sense that the answer is evasive.

The spell doesn't force creatures to speak.

You automatically know whether each creature succeeded or failed its saving throw.
