GURPS Thaumatology: Sorcery

This rules supplement presents sorcery as an innate magical power rather than a skill-based system. Spells are built as modified advantages, allowing magic-users to create and cast effects within clear, consistent rules that scale with the campaign’s power level. It includes rules for creating sorcerers, nearly 50 ready-to-use spells, guidelines for designing additional spells, and systems for improvising magic. A complete enchanting system covers creating or purchasing artifacts, while advice for players and GMs explains the mechanics and assumptions behind the system.
