From publisher blurb: Volume 13 of Awesome Powers deals with Sonic and Toxic powers. Sonic Powers can let you shake a building off its foundations with a mighty cry or a snap of your fingers, or place throngs of people under the spell of your song. The Toxic Suite allows you to use poisons, acid, radiation, and pathogens to not only devastate enemies but also to empower and to heal. You'll also find all new Enhancements, Limitations, and Advantages as well as several brand-new powers. Volume 13 has included a Random Power Generator compiling all powers from Awesome Powers 1-13. So now you can completely create a character without needing to flip through multiple books.
