Zorua -> Zoroark == Beryl || Peridot || North Obsidia: Event Chain (After a certain event, go to the Beryl Apartment Rooftop and start the chain by talking to Corey. Afterwards find Corey in Peridot Ward near the Pokestore. Finally go to the apartment near the Magma Gang Hideout and fight Zorua. Night required)
Sorry I need help with this one. Which event do I have to do and is the rooftop the one with the heliolisk and do you need certain weather or is it that it just needs to be night
