Here's one...
Screech (Su): Ba'atun can emit a loud, piercing and chilling screech as a free action. All creatures within 60 feet of the ba’atun must make a successful Will save (DC 17) or be struck by fear and be cowering for one full round. Each round that the screeching lasts, victims must make another successful saving throw at the beginning of initiative to be able to act. Only one saving throw per round is required (at the highest DC within range of each character), no matter how many ba'atun there are. This is a sonic, mind-affecting fear effect. The save DC is Charisma-based.
So, do you just want to repurpose that Special Attack?
