Adepts use their magic in a radically different way than other Awakened, by channeling magic through their bodies and minds; they do not cast spells or conjure spirits, nor do they typically have access to astral space. Instead, adepts develop powers that improve their physical and mental abilities.
Occasionally, the term adept can apply to magic users in general, and thus close combat magical specialists may be referred to as physical adepts.
Adepts are distinguished from street samurai, who also specialize in physical combat, but through more mundane (i.e. non-magical) means.
