From publisher blurb: Need to add more power to your Heroes Wear Masks games. Think your heroes are under powered or that the villains need a bit more POW! Well Avalon is here to help. Yep, Avalon has a new power system for HWM, and its a great big blast. This new power system really just an add-on to the core system, but allows for more options and more powers at even the lowest levels. We hope you will enjoy this addition to the game system. It is just an optional system and should be seen not as an official change to the core game, but an optional system for use.
