Oracle Ascension Coins
As you go about your journey in Final Fantasy XV, you’ll occasionally come across some Oracle Ascension Coins. These are actually a form of end-game currency that you can use to buy powerful equipment and accessories to help you out with the game’s tougher bosses and dungeons. Once you arrive in Altissia, you can head straight to Palsimo Street Station to look for an NPC who will gladly accept those coins and hand over some useful gear.
The NPC is located on the river level, in the restaurant where the Justice Monsters Five pinball machines are located. Look out for the man in the jacket and hat sitting at the table, talk to him, and you’ll be able to spend your Oracle Ascension Coins here.
