Caterwaul Concertina

By preparing your caterwaul, you can focus on your performance and sing to a wider audience. If your next action is to use Pahtra Caterwaul, you can affect up to five targets instead of one. If any allies in range of your caterwaul speak Pahtra, they can spend their reaction to join in on your Pahtra Caterwaul. If at least one ally joins the Pahtra Caterwaul, increase the frightened value of targets that fail their save by 1.
