Centesimal & Stability Variants
This supplement presents two optional system variants for Icons Superpowered Roleplaying. The centesimal system expands primary ability ratings from a 1–10 scale to 1–100, with alternative rules for calculating Stamina. The stability system adds Mental Stamina to measure a character’s mental and psychological well-being separately from physical fitness.
