OK, Played this char friday, Here are the results.
I changed my self into a hobgoblin walked into a group of goblins, surprised them and Whirlwinded them. Me 8 kills, goblins 0 hits. I moved into alot of rooms and disabled some things. The build works pretty well on the trash mobs IE Kobolds and goblins. I got plent of use out of Diplo, bluff, and intim. Think I'm going to take 9-10 lvl of martial rogue then take sneak attack fighter. Going to go vexing flanker / adaptable flanker.
Also DM said that we been struggling and gave us a one time chance to re organize the party so now we are a, Big Scary Barbarian that kills anything he manages to hit, a healbot cleric, a battle sorc using the spell shield thing from dungeonscape (this guy was the warlock, now he is much much more effective.) My martial rogue and another person that joined who may or may not stick with the game. He is playing a kobold monk/rogue that uses the draconic fist thing from dragon magic. We pretty much steam rolled most of the things we encountered this game.
Still open to options on where to take this build. Should I finish out 20 level's or just go for the sneak attack dmg?
