What is it about?
Cypher System provides a flexible foundation for original fantasy, science-fiction, horror, or superhero campaigns. It powers games such as Numenera, The Strange, and Old Gods of Appalachia, which adapt it to different worlds. Its d20 roll is part of its own resolution system rather than making it D&D’s d20 System.
02
At the table
The GM assigns difficulty and players apply skills, resources, and Effort to reduce it before rolling. Cyphers and intrusions add choices and twists during the adventure.
