Skills

This tabletop RPG supplement expands the use of skills with alternate rules, new skills, variable ability scores, skill synergies, extreme skill checks, and additional applications for existing skills. It introduces skill-focused classes such as the Executioner, Professor, Puppeteer, and Ritualist, along with a Grandmaster prestige class and options for several core classes. The book also includes feats, spell-hybrid abilities, specialized equipment, living-item races, and guidelines for balancing and implementing the new rules in a campaign.
