One minor one is an update in encounterabilities. You can now encounter Muckster, have a higher rate of finding Ivory Truckle, a lower rate of finding Embershed and Ivory TripTrop, and Celesteate, Keeper, Sentinel, and Nebulite can be encountered in the wild. The encounterability section of the Battle Enhancement update also allows for horde battles, much like Pokémon X and Y’s Horde Encounters and Pokemon SM and USUM Sos battles. You can now find different-species monsters in the wild if they are encountered along with a main related species.
