Gameplay Basics

  • Narrative-focused traits and abilities that quickly bring your character and stories to life in ways that make sense for the genres you prefer.
  • A simple dice-pool-based mechanic in which you add two of your dice results together and compare against an opposing roll. Uses polyhedral gaming dice of four, six, eight, ten, and twelve sides.
  • Player-centered choices allow for flaws and limits to manifest when the player feels they’re most effective. “Hitches” (dice results of 1) generate interesting immediate complications and long-term player benefits.
  • Session-based play recognizes that both one-shot stories and extended campaigns are made richer by focusing on the
    immediacy of what happens at the table—either in person or online.
