Monsters and Ruins

A fantasy role-playing system that combines elements of early and third-edition rules while reducing their complexity. It serves primarily as a player’s guide, covering character classes, skills, saving throws, talents, feats, multiclassing, and magic item creation; monsters, spells, equipment, treasure, and adventures are not included. The system uses ascending Armor Class and attack bonuses, three unified saving throws, and skills with variable difficulty. Characters gain talents and feats that represent class abilities, while progression uses unified experience tables and limits hit dice at higher levels. It supports classic and later character classes, including Rangers, Assassins, Illusionists, Bards, Hunters, and Necromancers, and allows unrestricted multiclassing.
