The epic feat Bulwark of defense requires you to be in a defensive stance which your build does not have. (Personally I think not having at least some of the defensive stance buffs on a pure fighter is a mistake.)

Stunning blow uses your strength modifier for part of the DC so you may have issues with it landing.

I like the Idea of going deep into the racial tree and it will be effective for some heroic levels. I think at 20 the majority of the racial tree should be droped in favor of stalwart defender goodies though. Typically you want the +25 prr mrr and +3 saves and +20% hitpoints. The perma blur is equaled or bettered by many good items and the stone skin has better item options and is no where near as usefull in epic quests. I think color spray on a int build could see some good continued utility for cc. Maybe you can get both good stance and keep color spray probably at the cost of 2 int though :(

Two weapon fighting is probably not as good a choice as single weapon fighting. But to maximize the utility of single weapon fighting you need to squeeze in magical training proficiency likely droping heavy armor training 3/3 mrr prr. the feat will power your know the angles and allow a orb in the of hand. A orb is a good place to up your positive spell power or acid and get some passive defenses too.

Dire charge I would call a must have for this build the dc is based off your highest stat and boosted by know the angles. A item boost could make it pretty much no fail in any content. Stunning blow with know the angles and those feats and some stunning gear should be fine most anywhere.

Can I use an off-hand orb with single weapon fighting? I didn't know that. Thank you.

You're missing some pretty important Kensei enhancements, namely last two cores and One w/Blade (+20 Melee Power).
You took Slashing feats and Gnomish Weapon Training; but none of the gnome racial weapons are slashing. Did you mean to use short swords or light picks?
FYI, the crit range bonus from T4 GWT doesn't stack with Keen Edge; you didn't take the latter, but wasn't sure if it's because you knew that or you forgot it. ;)
As others stated, Stunning Blow DC is STR-based; doubtful you can get your DCs high enough if you dump-stat STR even with tactics feats.
I agree you should invest in Stalwart D (usually 13-24 APs), unless you plan to use FotW, as defensive stance and Adrenaline don't play well together. You didn't list your ED.


With an overhaul this build should work; I guess I'm just not clear on what you're trying to accomplish by going INT-based.
