Truth

As an action, you touch a creature within range and ask them a question. The target makes a Wisdom save. On a failure,  they are compelled to tell the truth, although they are under no compulsion to answer the question. The target knows the spell was cast on them. On a success, they are under no such compulsion. 

You do not know if the target succeeded or failed their check.

At 5th Level, you can ask 2 questions before the effect wears off. At 11th level, you target no longer knows a spell has been cast on them. At 17th level, you know if the target succeeded or failed their save.
