Brown Magic (D20)
A supplement presenting Brown Magic as a force of construction, transformation, and manipulation. Its spells create matter, shape the elements, alter dimensions, and generate fields of force. The supplement includes three new Clerical or Mystical domains, revised classifications for a portion of the Player’s Handbook spells, and the Demiurge character class. Demiurges specialize in making and using magical items and gain access to higher-level magic more quickly than most spellcasters.
