White Mage

From publisher blurb: Blend the power of life with the arcane! With the new white mage class for Adventurer Conqueror King and Labyrinth Lord, you can add arcane healers to about any OSR game. Unlike their fellow magic-users, they have chosen to learn restoration magic at a cost of delaying their offensive magic. Originally appearing on my old blog, this class has been updated and expanded to include conversion details for Labyrinth Lord.
