Sorry for the double post, but I had a bit of an idea. I think that the Assassin Prestige class could be pretty flavorful for her, though I'm not sure which class to take to lead into it. Rogue is the obvious choice, but I'd want to pick something that's a bit more capable in melee, and the Rogue sort of frightens me because of how I've always been told that setting up sneak attacks is difficult. I'd probably try to invest points into Diplomacy or Bluff, with the goal of eventually being able to worm her way into the arms of a target out of combat and set him or her up for death.
I know I've asked a ton already in trying to get a concept going on, but might I ask for some help with this from someone? Preferably through PM, because I think I've posted in the recruitment thread more than enough as it is. @_@;
