Gaining Sneak Attack without Rogue?

[Person_Man]

OK, so please correct me if I'm wrong Deel, but from my reading of your comments, you want:

1) Pirate fluff
2) High Int ("quick wits")
3) Magic abilities/tricks/spells
4) Decent use of Crossbow & Rapier
5) Sneak Attack

How about a Psychic Rogue: Intelligence based powers, Sneak Attack, rapier and crossbow, excellent Skills. Not magical, but otherwise it seems to fit what you want.

Also, there's a part of me that wants to say Duskblade with Able Learner. great melee, decent Skills, tons of damage output that you could roleplay as sneaky. I'm not sure that's what you're going for though.

I understand your sentiment of not wanting to go with the Shadowcraft build or something similarly game breaking. But keep in mind that strong builds can always be roleplayed in a weaker fashion to suit your party level, where you don't use your best combo's unless. But it's very difficult to convince a DM to allow you to rebuild a weak character, unless you truly suck. Regardless, you'll probably be fine with your Rogue/Beguiler.
