The Vacuous Grimoire Volume Two
A digest-sized fantasy roleplaying reference for game judges, combining home-brew rules with the Open Gaming License System Reference Document. It presents old-school ability checks alongside racial and class abilities, replacing skill-based play with a faster, more streamlined approach. The rules add random mutations, arcane spell bungles, divine intervention, and other deliberately unbalanced effects. A complete magical item directory, plus a one-page character checklist for tracking party members, is included for use alongside the first volume.
替代规则（核心规则变体）骰子（主要为 d20）等级制（获得经验值并升级）基于属性/数值（STR、CON、PER 等）
