So wait let me get this right.
Someone suggested the kick to the dicebag VoP.
Then someone said Core Only, no multiclassing, no variants, blah blah blah. sorry, I really don't care. There is barely 7 combat useful feats in core, let alone 11. 1 Base class and Core only? What the hell is there to build? Monk, Duelist, maybe a level of Walker, end of story. We've already got one such build up too, you're not going to do any better. I've got a better idea. Optimize VoP Monk. Not build me a 1-int-wizard, not build me the world's worst Druid, build something where your goal ISN'T the worst damn thing you can think of. Because this is build optimized VoP Monk, not a build challenge based off the hardest handicaps you can think of and then make fun of how badly it sucks afterwards.
Any Race, any official book, say PB32 because everyone love it, no spellcasting, no psionics, no truespeaking, not even meldshaping, really none of that alternatives to magic other than ToB. You need a bare minimum of 5 Monk levels (average number before PrCing out) and be centralized on Monk or at least be based off exploiting a Monk trait.
Like for example I wanted to focus on those two extra attacks though FoB. Not wanting to come off as too Roguish I avoid SA and instead capitalize on Iaijutsu Master, because a VoP Monk can own and FoB with Daggers. Not to mention Dark Moon Disciple makes damn near everyone Flat-footed against you. It compliments very well. I could start with 8 Charisma, assign the +2 from VoP to it and read a +4 Tome. I'm not Charisma based at all, hell it's only +9d6+18 per hit, but I am building off the Monk's FoB and using the Monk's AFC in order to use it. It's smart building and I'm not coming off like my PrC is the reason I'm useful. Opposed to extrema of say, posting a Bard/Sublime Chord that can use Unarmed Strikes.
In fact, come to think of it. I think like the Iaijutsu route. Daggers are piercing weapons, Dragonborn get their dive ability. If Dive & Battle Jump can be used together you've got triple charge damage, Iaijutsu, and Passive Way Tripping. I need to read up on it.
Edit
You can't jump from more than 30 feet above your opponent, nor can you effectively battle jump while under the influence of a fly or levitate spell or effect, as you have to hurl yourself down on your foe. ~ Battle Jump
Doesn't include mention of real flight, just the spells. Fly & Levitate are move of a ignore gravity effect, and you certainly can hurl your self downward in a dive. It's literately what you're doing to begin with. Looks like it would work.
