Breeding
Breeding Regional Pokémon
To breed a regional Pokémon you need to have the regional Pokémon you want to breed to be holding an Everstone. (Only one parent has to be holding the Everstone to pass down the regional form, note that breeding two regional forms together still requires one to hold an Everstone.)
Example:

Passing Down Nature
Natures are passed down when one or both parents holds an Everstone (the same as passing down regional variants). If both parents are holding an Everstone the Nature is randomized between the two of them with a ratio of (50/50).
IV Breeding Guide
Destiny Knot:
The first thing you need to know for breeding high IV Pokémon is how a Destiny Knot works. These can be obtained by either buying or crafting them.
Crafting Recipe:

When breeding Pokémon with no items, only three stats are inherited from the parents while the other three are randomized.
Example:


Breeding with a Destiny Knot passes down five stats from both parents instead of three. This does not stack, meaning the maximum that can be passed down is five, with one stat always randomized.
Example:
