Hypothesized subclasses: Sun-Sun, Sun-Moon, Sun-Earth.
From research I've found that there will likely be two Mystic Subclasses. There implimentation is too far away to know what abilites they will have.
5/15/05: Latest News, "The mystic subclasses will not be "sun-sun" or that "sun-earth" junk of information that you recieved. They will be put into determined on what the mystic specializes in. That and the mystic's guild will be split into two. Mystics and Dark Mystics."
*wanted* Various Mystic subclass related pictures and more indepth information. Contact me with suggestions, corrections, pictures, and information at RhoneCL@comcast.net
