Some may have seen the pixie thread I posted earlier. I was given good advice, and ultimately I decided to drop pixie for something with less LA. I still want a sneak attack optimized build though and without the invisibility effect, I'm unsure as to how to constantly sneak attack.
Here's my character creation info. I'm allowed four sources (PHB,DMG,MM1 are automatic though, don't need to buy them), two base classes and two prestige classes. However, I can trade a source for a base/prestige class, or vise-versa (only allowed to do this once per class though). ALSO, I can take a penalty to all gold received in the game by buying an extra source or class, but this is not preferred. We start at ECL5 with 32 point buy. Fast casting prestige classes are not allowed.
Here's what I was thinking so far. First of all, exchange one prestige class for an extra base class. Next, I would take swordsage, rogue, wizard, until ten, then take unseen seer. This would land me with ~9d6 sneak attack dice right? Any other ideas? I know this isn't the best way to do this, so I'm asking you guys.
I believe I was also told that Swashbuckler+Daring outlaw would be good too so I could potentially sacrifice a source.
How would you do it?
