I'm trying to shiny hunt zorua in the game. I going to need increased chance of finding a shiny.
You need to obtain all Pokemon of the alolan pokedex (without mythical, but you also need the ultra sun exclusives).After obtaining, go to the Heahea City Game freak office. The Game Freak office is located on the second floor of the third building to the east of the Pokémon Center; immediately to the southwest of the Dimensional Research Lab.Then, the game director of the office will give you a shiny charm.
Enjoy your shiny zorua sos chaining!
