The three special roles (assassin, zenmaster, and valkyrie) are by invitation only. The assassin is the only one you can do in the early (okay, the middle) part of the game -- Scanthril gives you a task to complete, and in return, gives you an item which allows you to become an assassin.

For the zenmaster, you have been finding tomes of creation along the way. Once you have the full set, you can become a zenmaster. You won't find the last tome, though, until you get to the last dungeon and the game is almost over.

For the valkyrie, there's an act you can perform in the last dungeon which will gain you an invitation to become a valkyrie. The person who does this act, however, has to be a female ('cause there are no male valkyries... a clear case of sexism if I ever heard one [img]smile.gif[/img] ).

These last two take place very late in the game, and render those two roles close to useless... for this game. However, you can reset adventures and play with those characters again, and start over from scratch.
