As a standard action, a voonith can unleash a bloodcurdling howl. All creatures within a 30-foot-radius burst must succeed at a DC 15 Will save or become dazed for 1 round and then shaken for an additional 1d6 rounds. Any creature that makes a successful save against a voonith's howl is immune to the same voonith's howl for 24 hours. This is a sonic mind-affecting fear effect. The save DC is Charisma-based.
