In the RPG we are creating, those artificial lines have been erased. Who is to say that a fighter wouldn't know a healing spell? Who's to say that a wizard wouldn't use a sword? In our game, the answer is - nobody. Any character can pursue any skill set so, for example, you could have a character that can cast a magical attack spell, move quietly, wear armor, and uses a bow. Such a jack-of-all trades character wouldn't have the mastery as a strongly focused character but it is possible. If you wished, you could select skills to build a traditional fighter or rogue or wizard or cleric. Or you can have a primary focus area but pick up one or two other abilities from what would be traditionally considered another class. A rogue that knows an invisibility spell? A fighter with Magic Missile? Look out!
But what about character advancement? I promised to address that issue in this post but I'll put that off until the next post... I promise!
