From publisher blurb:
In the early days of the game, the Illusionist was introduced to provide a slightly different take on the magic-user, even before spells had categories (Charm, Illusion, Evocation, etc). Second edition created specialists of each magic type, but did away with the uniqueness of the Illusionist by letting a general mage have access to all spells.
This is an attempt to duplicate the uniqueness of Illusionist, but with a different sort of magic, that of Enchantment (and Charm). The Enchantress casts spells that manipulate people, either through charm, inducing emotions, or putting them to sleep, including 30 new ones (at least to OSR, they are culled from later sources).
Although primarily intended for the 1st advanced edition of the worlds first fantasy role-playing game, tables are included for the original and expert editions.
