FailureEach round of the spell's duration, you can
Sustain the spell to ask a different question and attempt to uncover the answer. For each question, the target can attempt a
Deception check against your spell DC; if the target succeeds, you don't learn the answer, and on a critical success, the target gives you a false answer that you believe is truthful. Once you've asked the target a given question, asking it again, even with a separate casting of mind probe, produces the same result.
Critical FailureAs failure, and the target takes a –4 circumstance penalty to
Deception checks against your questions.
