|Act II - Octagonia, girl outside the Casino||Vest for Success|
Once you return to Octagonia in Act II and return all of the monsters back to humans, you’ll find a girl outside the Casino. She won’t have the usual quest marker but when speaking to her, she asks you to get a Statue from Richie in the Casino. Agree to help and then make your way to the VIP area to find Richie and begin the quest officially.
You’ll need to hit a Jackpot on the Roulette table, something that is entirely down to luck. There is however, a few little tricks you can do to push it in your favor. To begin with, you’ll find a Bunny Girl near a Token Tower who will fill you in on if someone is about to win the Jackpot soon. Wait for her to say the line "But I got a feeling someone’ll be winning the whole pile before long", if she doesn’t say this then rest at the Inn and return the next day. You’ll need to keep repeating this until she says the line.
Once she says the line it’s time to play Roulette so make sure you create an autosave by exiting and returning to the VIP area. There’s no surefire way to achieve the Jackpot but there are two methods you can try. The first is to place a bet on the numbers 12 and 14, these numbers appear to be common and have a better chance to hit a Jackpot. You other method is to put a bet on every number, this secures your bet and guarantees that if there’s a Jackpot, you’ll have the number in question. You could be fortunate and hit the Jackpot in a few spins, you could be here hours, either way once you hit that ever elusive Jackpot, speak to Richie to complete the quest.
