Compel Secrets

You reach out and touch a humanoid creature. They must make a Wisdom Saving throw. On a successful save nothing happens.  On a failed save, the creature must reveal one of their own hidden dark secrets. Once the humanoid's  secret is revealed, the caster as well must match the dark secret with one of their own. After the spell is cast, the affected humanoid is aware of the spell and its intent. The humanoid cannot avoid answering with a lie, or by not answering at all. The secret can be spoken in any language that is known by the creature.
