I am condensing all of the Mafia Wars Bangkok Collection and Boosts (for boosts from businesses, see the faction business post) from the first two episodes in along with the collections from the recently released episodes. Note: Currently, Episode 5B (Dragon Head) does not have a collection associated with it.

And that's it so far for Mafia Wars Bangkok collections. For some reason Episode 5B (Dragon Head) does not have a collection, if that changes, I will update accordingly.

All in all, I'm fairly disappointed with these collections and especially the boosts. They are definitely a step down from Moscow collections and boosts. The Boutonniere only gives +10% payout on jobs, which is essentially worthless - even if you got 10 of them from re-vaulting, it would only be an extra $B5,000 or so from even the best jobs, which is just over 1% of the cost of the best loot from the faction store.
