This build is sort of an "inversion" of the Assassin (..Left Hand of Gargauth) build that I last posted.
Entropic Warrior | NWN2 Character Builder
Where the Assassin build used stealth to lower an opponents AC (as a "flat-footed" attack). This build is "in plain sight" - and feints to achieve the same effect.
Again where the Assassin build used stealth (and knockdown) to overcome spell-caster attacks, this build is "in plain sight" and simply "shrugs off" magical attacks as if they had no effect (or very limited effect).
The Assassin build was fairly limited to attacks against single opponents. This build is decent against multiple opponents.
The Assassin had additional damage against non-critically immune, while this build can add additional damage via Divine Might and Epic Divine Might.
