If you have not yet played through Episode 7 of Mafia Wars Bangkok, note that there is no "Choice Points" - in other words, you never have to pick between Triad or Yakuza.
Here are the four loot items available in Episode 7. Again, there are no choice points, so these are available to everyone:
Titanium Katar: 35 attack, 50 defense (weapon)
Royal Thai Marine: 33 attack, 49 defense (armor)
Chain Viper: 46 attack, 33 defense (currently an armor, but will become an animal)
Lamang Motorcycle: 49 attack, 34 defense (vehicle)
So, with that said, here are the new best-in-slot pieces (not counting Chop Shop / Faction Store items):
Offensive: Nak Kha Shotgun (47 attack) - Episode 6, Chapter 3 (Triad-only)
Defensive: Titanium Katar (50 defense) - Episode 7, Chapter 2 (no faction requirement)
Offensive: Lamang Motorcycle (49 attack) - Episode 7, Chapter 2 (no faction requirement)
Defensive: Raed Armored Sedan (47 defense) - Episode 6, Chapter 2 (Triad-only)
Offensive: Ninja (47 attack) - Episode 6, Chapter 3 (Yakuza-only)
Defensive: Royal Thai Marine (49 defense) - Episode 7, Chapter 1 (no faction requirement)
Note that there is an overlap between two best-in-slot items. In Episode 6, Chapter 3, both the Triad and Yakuza provide a "best" item (Nak Kha Shotgun and the Ninja).
There are a couple ways you can work around this:
1) You can stay at 3-star mastery until you collect all you need of one of the items, then switch over to the other faction. For example:
-Master the jobs in Episode 6, Chapter 3 as Yakuza up to 3 times. Do not "Finish" the boss and move onto level 4 mastery.
- Repeat the job in question over and over again until you have all the Ninjas you need.
- Master the tier for the 3rd time, and then switch over to Triad on the last time through. Now you can collect all the Nak Kha Shotguns that you need.
2) Trade for whatever piece you need.
This *could* be easier if you can find a trading partner. Finding a partner would be tough though! I don't recommend this route unless you plan to do this with a friend.
3) Ignore the Ninjas.
This is what I am doing. It's only a light upgrade over the Shturmovik and you can buy a better offensive armor in the faction store.
Additionally, there is a new "Armor Shop" coming just like the Chop Shop and Weapons Depot, so there will be even more high quality armor available which will be better than the Ninja.
I'm just going to sit this one out - there is plenty of other stuff to collect!
Job Mastery Items:
For mastering Episode 6, the reward is the Xinthriy Executive Jet: 78 attack, 125 defense (vehicle; this will replace the Royal Thai Elephant which will become an animal).
For mastering Episode 7, the reward is the Thai Giant Centipede: Attack 133 Defense 80 (weapon; will become an animal).
And that's pretty much it for these two episodes! For all the serious players out there, there is now plenty of $B to get and plenty of loot pieces to collect. Enjoy!
