Purple Magic (D20)
A supplement for fantasy roleplaying games that presents Purple magic as the force of endings, death, unlife, cold, and the frozen void. It includes three new Clerical or Mystical domains, revised classifications for approximately one twelfth of the Player’s Handbook spells, and new effects adapted to Chromatic Magic Theory. The supplement also introduces the Devolutionist, a spellcasting character class that draws on the ultimate void to wield necromancy, elemental cold, and powers that drain energy from creatures and objects.
