Uncommon, Abjuration, Cleric
Domain Secrecy
Cast [two-actions] Material, Somatic
Range 30 feet; Targets 1 creature
Saving Throw Fortitude; Duration varies

You quiet the target's voice, preventing it from giving away valuable secrets. This doesn't prevent the target from talking or providing Verbal Spell Components, but no creature more than 10 feet away can hear its whispers without succeeding at a Perception check against your Spell DC, which might interfere with Auditory or Linguistic Effects as well as communication. The spell's duration depends on the target's Fortitude save. After attempting its save, the target becomes temporarily immune for 24 hours.

Critical Success The target is unaffected.
Success The duration is 1 round.
Failure The duration is 1 minute.
Critical Failure The duration is 10 minutes.
