You force truth into the heart of your target. Choose one creature within range. The target must make a Intelligence saving throw. On a failed save, it is compelled to answer one question you ask each round (no action required). It must answer truthfully to the best of its knowledge, though it can still be cryptic.   While affected, the creature has disadvantage on Intelligence checks and cannot knowingly speak a lie. It repeats the saving throw at the end of each of its turns, ending the effect on a success.
