Here's my version of him. Though, it isn't final, because as new books come out with new feats, PrC, and other material then I end up re-vamping him anyway. But here is my version of Jarlaxle so far that I've used in my games. This was made almost a year ago, and with stuff like the Player's Handbook 2 and alternate class features recently released, I believe I'll have to remake him again.
