Credits

Credits are the only currency in Lust Doll Plus. They can be used to buy items, clothing, services and anything else that's on sale.

Obtaining Credits
Lust Doll can earn credits by working at a job, finding them in loot chests, or selling unneded items. There is also an option to start off with however many credits you want.

Server at Roxie's Diner
Lust Doll may approach the manager and ask to work as a waiter. They would accept and give the uniform for free, based on Lust's gender.

Lust will then be able to work a maximum of 4 shifts a day for a random amount of credits, the amount varies by what happens during the shift:

Stripper at Gentlemen's Club
Simply talk to the boss at the top-most room to get the job. Available as long as Lust isn't tired.

The chance of getting a better event increases with the Ero stat: Any show counts; counter only resets if you accept getting cuffed.
 * 0~100 + [Ero] = RE
 * ≤33 RE = Not your day
 * 34-66 RE = Normal
 * Did 0 shows, ≥67 RE = Sexy fever
 * Did 1 show, ≥100 RE = Sexy fever - Cuffed
 * Did 2 shows, ≥90 RE = Sexy fever - Cuffed
 * Did 3 shows, ≥80 RE = Sexy fever - Cuffed
 * Did 4 shows, ≥75 RE = Sexy fever - Cuffed

Note: here seems to be a switch that prevents you from obtaining Sexy fever - Cuffed event 2 times in a row (regardless of your choice during this event).

Fighter at Devil's Drink
After learning the secret phrase from the all-knowing hobo and accessing the arena, Lust can beat up people for the show. The basic reward is 100, but it can be increased if you're willing to get handicapped: Enemies:
 * Highwayman
 * Bandit Girl
 * Wildcat
 * Lin Lin (after first encounter)

Bouncer at The Rock
Lust Doll may approach the bartender for inspection, 5 or more strength is needed to get the job. Each shift costs 20% of your current stamina.

Selling
Bucks For Bang allows to sell almost any item and clothing for half the price. There's also a portable seller.
