True Sorcery
A flexible magic system for d20 and OGL roleplaying games replaces fixed spell slots with spells built and shaped by the caster. Players determine each effect’s range, speed, and potency, combining more than 50 spell effects such as creating matter, flight, and teleportation. The book includes a spellcaster class, new skills and feats, example spell constructions, and rules for creating single-use magic items and powerful artifacts. Optional rules cover taint and true names, with adaptations for several d20 settings and an alternate Arcanist class.
