Chaos Effect: Godlike (d20)
A superhero campaign supplement for OGL and d20-based systems, centered on a character whose abilities increase to godlike levels while control and humanity decline. The campaign explores power use, evolving weaknesses, changing relationships, and the consequences of a teammate committing a serious crime, leaving the group to decide whether redemption is possible. The supplement provides guidance for integrating the premise into a campaign, power scales and control methods, character archetypes, sample cosmic, divine, elemental, and other powers, non-player characters, adventure hooks, and nearly 20 new feats.
