I seem to recall a build that did this, utilizing as many strength and attack boosting rages, plus kiai shout(?) and that thing that ronin do, to lower your AC to negative levels, but make a charging full attack, and then karmic strike/robilar's gambit was in there, so your hellishly powered hits would go full attack, and if it survived and attacked you, you nailed it with superpowered AoO's. I remember seeing it, but can't find it. It's somewhere on gleemax, I'm sure. Anyone know what I'm talking about?
