The Critonomicon

A collection of critical hit, fumble, and magical mishap tables for role-playing games that use critical results. It includes quick d6 tables, more detailed d20 and multiple-dice charts, and larger tables with hundreds of possibilities. Results cover specific weapons, mounted or winged opponents, and spell fumbles organized by spell level and school of magic.
