Grace sent me this screenshot when she fight in Brazil :

She got 5x of Weapon Parts in 1 fight.
We know in Brazil, 1 fight costs 4-5 Stamina. Leo has explained it
here.
Low-medium level players (perhaps under level 450), have it 4 Stamina, while bigger fish has to spend 5 Stamina per attack.


That's why you can have a chance to get loot drop 5x times!
I have spent small amount of Stamina using my low level account and take this screenshot :
I used Brawler bookmarklet but feel not satisfied and decided to do manual fight, just to see the loot drop.

Here they are :
Conclusion :
If you spent 4x Stamina - you will have a chance to get 4x times loot drop
If you spent 5x Stamina - sure you will have 5x times loot drop
Frogi has tested on fighting in Brazil.
He spents lots of Stamina to get the info about loot drop, XP gained, etc.

For 8235 Stamina spent, he found that the XP gained is good. The loot drop is poor, only about 7% and low drop on Victory Coin.
Here is the screenshot of his loot drop :

Nah, each city has their own good and weakness, feel free to choose which city to spend your Stamina on.
Happy killing!
PS : Thanks to Grace and Frogi for the screenshots!
