Magicians range from powerful wizards to vile cultists. They draw on raw supernatural energy to fuel their eldritch fires. This energy often infuses the worlds in which they live, and is drawn forth with elaborate rituals, words of power, runes, or perhaps even dark sacrifices.

Wizards are often quite weak early in their careers, but are forces to be reckoned with as they become powerful sorcerers.

Backlash: When a wizard rolls a 1 on his Spellcasting die (regardless of his Wild Die), he is automatically Shaken. This can cause a wound.
