Wizard

From the introduction:

Among wizards, there are few who devote themselves to learn and practice the secrets of the Arcane Healing arts. Their unique ability to heal earns them a warm welcome on most places and adventuring groups.
...
Many wizards employ familiars to assist them, but only a few have unlocked the power of their magic through the familiar itself. For them their familiar isn't just a sliver of their conscience, but a true friend and powerful companion.
...
Wizards who do not specialize, known as Generalists, apply their intellect to the arcane magic as a whole, and because of that have the most diversity of all arcane spellcasters.
