This is a new DLC episode in which you control Sazh. It has two main purposes - to obtain 30x Fortune Medal from Chronobind or Serendipity Poker, and to find out who Chocolina really is.
After the initial scenes talk to the casino owner to receive 10000 coins, which is a good amount to start gambling with. If you ever run out of coins, talk to the owner again, but be careful as there's a limit to how many times he'll help you out.
Instructions for Chronobind and Poker are provided with the game - the absolutely best way to get Fortune Medals is to go and play poker, choose a buy-in amount of 1000 coins, and then select "All in" to bet all your coins. In many cases. the other three CPU opponents will fold. Every "All in" bet you win nets you one Fortune Medal. Continue doing so until you get 30 medals, and then talk to the casino owner to obtain Sazh as an addition to your monster menagerie. Sazh comes as a Synergist.
Now go to the leftmost house in Serendipitiy and talk to Chocolina several times. She wants you to look for missing chocobo chicks and there's seven of them.
HAUGHTY - Found near the chocobo races building. Talk to it and at the Live Trigger choice answer Square . The chick now starts following you around, so return to Chocolina. Do the same with other chicks you find.
SLOTH - Found south from the giant roulette wheel. Talk to it and at the Live Trigger choice answer Square .
WRATH - You need to follow this chick around and mash X once nearby in order to initiate the talk. First it's running around near the chocobo races, then inside the card games building, then back outside south from the roulette wheel, and then it reaches its endurance limit near the chocobo races building. Chick obtained!
NEID & LUXURIA - These two are near the big roulette wheel. Talk to Luxuria to get a letter, and deliver it to Neid, who ran to the balcony south from roulette wheel. Talk to Neid, who mocks Luxuria for not bothering to come deliver the letter in person. Now talk to Luxuria near the chocobo races and take the chick back to Neid. Presto.
GREED, ACEDIA & FAULHEIT - Go to the casino room and talk to one of three chicks on the table. At the Live Trigger choice pick Square to have Greed join you.
When Greed is delivered to Chocolina, press Square at the Live Trigger and you're done!
