I've been wanting to shiny hunt for so long now (especially for a Zorua) and just got my last gym badge. I found Zorua in the wild and am currently attempting to shiny hunt them.
I've had pretty high chains yet no shiny. Do I have to have beat the Elite Four and Champion at least once before I can shiny hunt?
Best Answer
There are no evidence that shiny hunting requires you to beat the Elite Four.
According to this Reddit:
The only thing that can actually increase the chance of finding a shiny is having the Shiny Charm, which you can get from Professor Birch after obtaining all Pokémon in the National Pokédex.
