Really want a Gible with rough skin, i know it's a hidden ability. I'm EV training right now, and really need one with the Jolly nature and this ability. That being said, anyone know how and where to get one? Oh and if you have one, mind trading me it? Promise to give something good in return, please guys lol I'm in a crisis!
Hidden abilities can be gotten on Safari pokemon or (sometimes) on Horde pokemon.
Your best bet is to find someone with a Gible Safari willing to let you in. If you don't want to do that you can always try the Honey/Sweet Scent method, where you purposefully attract Hordes. I believe Gible shows up in the Badlands just north of Lumiose so you should do it there.
