Edition-aware reference library
Rules Codex
Search plain-language player rules alongside edition-specific races, species, backgrounds, feats, classes, mundane equipment, spells, and magic-item collections. Every result is tied to a game system and edition so rules from 2014 and 2024 never quietly blend together.
One library, separate rulesets
My RPG Source stores each game system and edition in its own Codex collection. Even when two editions use the same term, their entries are kept separate so later updates, comparisons, and builder links remain dependable.
The Rules collection uses original, beginner-friendly explanations. The Races & Species, Backgrounds, Feats, Classes, Class Features, Mundane Equipment, Spells, and Magic Items collections preserve licensed SRD material with visible source and edition labels.
