You duplicate the powers of up to LVL classes. You
get your total XP in this class to spend on each of these classes to see
what level you are in each class. You must meet the stat and level
requirements of each class you duplicate, but these requirements do not add
to each other. You get the spell/psi progression, "Level:"
abilities, and rogue-like abilities of each class. You do not get the HD,
weapon proficiency progression, TH, or saves of the classes.
