I have a Male Hidden Ability Emboar that is Legit that I got with the Event. I want to pass its HA down with Breeding via Masuda Method. Yes, I want a Shiny, and I need some form of help before I commence this plan. Do you have any ideas on what I can do to pass down the HA besides hacking a Female Emboar?
Breeding a Hidden Ability Emboar with a Ditto will still have a possibility of passing down its Hidden Ability. You'll just have to keep breeding until you get a female Tepig with its HA. The chances are slim, but there is a possibility. The rest is just Masuada Method stuff that you already know.
Good luck with your Shiny Reckless Emboar!
