For one, turns out only the function of the build is remaining. It's going to be sneaky, and it's going to hit stuff.
On the other hand, it is now a tibbit soul seater with a dip in morphling for the slam, who will be using Ring of Natural Attacks +1 with aptitude weapon on it for Shadowblade, along with a level of Hit and Run Fighter, and I am currently finagling how to get the feats for both Shadowblade (Since I have to enter it through feats because swordsage doesn't have full BAB, which I need for Soul Stealer) and Soul Eater itself.
