Prestige Class Help ~~~ Assassin

[Hexblade]

Hail, Knights of the Homebrew Table. I require thy assistance in a most worthy quest. I must convert a captured assassin into a more honorable comrade. We require his skills, but he does naught but curse us and attempt to slaughter us in our sleeps! Do thy have any brilliant ideas, o gracious ones?

Translation: Hey, Playgrounders. I need your help changing the assassin prestige class into something that doesn't have requirements of being evil. I want to keep most of his skills, maybe changing some, but I want to keep his general idea. I have an upcoming game, and a player wants to play an assassin. I told him no, because it's evil, and I might be able to make a prestige class with the same idea. So now I need your help.

Ideas:
Mine:
Make him into an Arrow-esque hunter who hunts corrupt officials
Change his skills so he is more of a rogue focused on the sneak attack ability but nothing else

Feel free to suggest your own.

This isn't homebrew, and you might have already thought of this, but the slater of Domiel from the BoED is more or less what you want, perhaps with minor tweaks.

[Hexblade]

Maybe. If I change it to Chaotic Good and change the flavor a bit, it might work. Thanks!

Even simpler. Keep the class as is, simply remove or rework the MWAHAHAHA EVIL requirements.

If Rogues with Sneak Attack aren't always evil, then what amounts to a specialist in the art doesn't have to be, either.

[Hexblade]

Fair enough. But I was hoping for a bit more of a revamp, where he isn't a hired thug, he's a vigilante that goes out and takes down the corrupt. Maybe with an ability that's something like knowing who is corrupt in a certain city, like a Knowledge check but always succeeds?

WotC published an official variant (http://archive.wizards.com/default.asp?x=dnd/prc/20070401a) that literally changes the "kill someone" requirement and nothing else, as far as I can tell. There's also the Vigilante class in Complete Adventurer. You could either use that, or just steal some class features.

This looks cool. Thanks!
