Since Zizi and Duck have both apparently fallen off the planet, Party C finds itself in need of a stealthy class, ideally a Ninja.
The Ninja is what it sounds like. Stealthy death. Ninja are stealthy, acrobatic, deadly, can do martial arts, and get a variety of kind-of-like-magic ki powers. Also kunoichi get jiggle physics based distraction powers. Believe it!
But other classes, depending, might be fine. Get in touch. Mentioning C in particular because it most imminently needs new players. :O
EDIT: C got new player. It's F and E that have openings now. I'll post details later.
