Sorcery

From the White Wolf Wiki, the most complete White Wolf reference

Sorcery is a more sophisticated and demanding form of Essence manipulation than Charms. With Charms, the Exalt focuses Essence through her Abilities, while, with sorcery, she focuses it through sheer will alone. Sorcery features three levels of initiation: Terrestrial Circle, Celestial Circle and Solar Circle. Sorcerers may also practice necromancy, but advancement in one art inhibits development in the other.
