Yellow Magic (D20)
This supplement presents Yellow magic as the arcane principle of health, vitality, passion, and the power of life to survive and grow. Its practitioners use study, reason, and magical technique rather than faith to heal wounds, cure diseases, and even restore the dead. The supplement adds three Clerical or Mystical domains, reclassifies a selection of Player’s Handbook spells within Chromatic Magic Theory, and introduces the Physician class. Physicians combine practical doctoring with arcane magic, using their hands to heal or, when necessary, harm.
