Multiclass silliness

[zapbib]

Ok, I had a character concept: a duelist that focus on disabling is adversary, so he can gloat aside them. I realised that the best way to go doing it is by taking a lot of multiclassing. I need advise to see if I can do something similar but simpler

so the build(20 point buy):
Take half-elf
10 16 14 8 10 14(+2 on dex)

swashbuckler: Exotic weapon proficiency(Katana),Weapon focus(Katana)
slayer, bounty hunter:
monk, master of maneuver: improved dirty trick, slashing grace(Katana)
Slayer, bounty hunter:
Slayer, bounty hunter: canny tumble
Fighter, lore master: confounding tumble deed
Fighter, lore master: greater dirty trick,quick dirty trick

The purpose of it all of course is to always be able to do dirty trick through sneak attack and stack all the possible dirty trick debuff, that way the enemy can only remove at most 2 if he does nothing.

I think I can use the weapon bonus and finesse for the dirty trick since the bounty hunter learn to do them instead of sneak attack. It might not be 100% sure by raw but I think it's an acceptable view.

I took the katana because I don't like scimitars, I do realize that a scimitar is obviously better because I trade 1 damage for 1 feat.

So, how would you have done it? Or is there any improvement you can see?

So hum, shameless bump and an additional question: What to do with the empty hand, I could wield a shield, but let's say I want something else, any suggestion?

You only get to use weapon bonuses (like focus, finesse, enhancements) with maneuvers if you are using the weapon for the maneuver. So if you are using the dirty trick to throw dirt in their eyes, you're not going to get to use your dex (unless you take agile maneuvers).

As for weapons, I'd go with a monk weapon. A temple sword would work with the feat to make a one handed slashing weapon good for swashbuckling. That way you get to make use of your monk flurry too.

If you want to go for some dirty trick maneuvers, you might look at the Cad fighter archetype instead of Lore Warden.

Another possibility is to go the Brawler route instead of Fighter: Once you have Combat Expertise, you would have a lot of flexibility changing out your maneuvers on the fly. Natural attacks, so I can't disarm? I retrain into Trip. Too many legs or flying? Switch to Grapple or Dirty Trick.

Maneuver master don't get flurry of blow, they get flurry of maneuver that allow them to make one maneuver free on top of normal attack, even if it's usualy a standart action. They can use any weapon for it.

The bounty hunter archetype at lvl 2 can replace his sneak attack damage die(which he get at lvl 3) with dirty trick maneuver. Since he still do his normal damage and replace his sneak attack I assume it's acceptable to say I use the weapon to do the dirty trick. I'll leave the GM rule on that.

Brawler was an option, the main problem was feat starving, Lore master get s combat expertise for free on top of his bonus feat.
