The only reclass limits are ones set by gender. A female character of any class cannot access Barbarian or Wizard ever. Conversely, male characters cannot access Pegasus Knights or Troubadours. And obviously any Advanced classes that can only be accessed by that class (Berserker, Warlock, etc) are restricted as well. All other classes are open to both sexes. I specifically made each sex have one unique physical class and one unique magic class to be the most fair.
